How to "Come out" 2 a GG LADY , a former Coworker

I would appreciate the advice of  unbiased GG Women how to "Come Out " to a very good friend.

Since yesterday morning late I've been in quite a quandary.

Yesterday morning about 11am I got a  phone call on my smartphone with "PRIVATE CALLER" displayed as the Caller I'd. So I didn't pick it up. A few minutes later another similar phone but this time b4 I could pick up the phone the Caller had left a Voicemail message with her name and phone number.  She said please call her at the number in the message.

It was from my "best" former coworker and friend, A VERY NICE GG Lady (a couple years old than i) & friend of mine (from a previous employeer we both worked for during the late 1980s thru mid 1993 when she changed jobs.  Early on while coworking together, we discovered we had birthdays a couple of weeks apart so we would have lunch together at a nearby restaurant, either a few days after mine or a few days before hers, mine in late November  and hers in Mid December. After she changed employer, for several years we would get together to celebrate our birthdays whenever our schedules allowed. In mid 2000s we lost touch with each other

She said she recently moved back from West Coast, a was living in same nearby EAST COAST neighborhood,  as when we wwere coworkers. She wanted to know if we could have lunch together on the January 16th at our usual restaurant we use to celebrate our birthdays at and renew our friendship during lunch together.   Yet to return her call.

For u to understand my quandary i need tell my History of Dressinging enfem.  I've been a closeted XDRESSER since my junior year of High School until recently.  Neither former coworker nor SOGGF was ever was aware I was a closeted XDRESSER.

But since early October 2015 I've been living 24/7 fully ENFEMME with my SOGGF when she came home 3days early from a 3week business trip and discovered me wearing one of her bras, panties and pantyhose and a sexy spandex bodysuit and a mini skirt.  Since the morning after she left 4 her 3 week business trip I had been wearing nothing but her clothes around the house SHE WAS ROYALLY PISSED, I Had been wearing her outfits around  house whenever she she went on a multiple day out of town business trip.  Apparently she previosly noticed every time after she came home from  trip her dresser drawers had been riffled thru. Thus this time she came home 3 days early on the day our maid service came thinking maybe the maid was responsible.  When she saw me dressed up She said aha it's you riffing around in my dresser. She said well since you obviously like wearing my outfit, then for NEXT 3 WEEKS THRU HALLOWEEN NIGHT and for my firm's Halloween costume party YOU WILL 24/7 WEAR NOTHING BUT FEMININE ATTIRE including makeup. And wear it in PUBIC INCLUDING WEARING MY SPARE PAIR pof Breast Forms semi permanently adhered to your chest with the same waterproof surgical adhesive I use. ( she thinking it would be fitting punishment for me,  not realizing it would give me a reason to wear FEMININE ATTIRE in public again, something I hadn't done since early childhood when one Saturday playing with kay my nextdoor neighbor a girl that I played most afternoon, her mother about 1pm said Jammie go home Kay has a ballet class at 330 to get ready for.  K THRU a fit  I would go unless Jammie does her mom said little boys don't take ballet classes  I've already paid for yours and gotten 2 complete ballet outfits 4 u as required.  You will go ..kay said no again crying I want to play with Jammie unless he goes I WON'T. Then Kay's mom said Jammie since you and Kay are same height and weight I think Kay's 2nd outfit would fit you also. And since both your hair are nearly same length (I was 6 and never had a haircut nor had Kay) I can do hair up the same way. Provided ur mom is willing to pay for a class for you would you like to go ? I probably said okay, I like playing  with girls, 10 minutes later my mom is at Kay's house and Kay's mom has handled me AND my mom Kay's 2nd ballet outfit including a little girls panties and little girls ballet bra and pink leotard, tutu skirt and pink tights and pink ballet shoes.  Kay's mom escorts me and mom to a quest bedroom for me to change into the ballet outfit  20 minutes later in come Kay and her mom. Kay's mom says Jammie now I will  do your hair up in a ponytail tail with a pink ribbon bow just like Kay, the outfit fit me perfectly as did the ballet shoes.  Next thing I knew mom says to Kay's mom they could be twin sister's let's get some Polaroid pictures. They are so cute,  Jammie is now THE GIRL a I always  thought i would have, LETS CALL him Tammie the name I would have given a girl baby) thus thru 3rd grade I took ballet classes as Tammie with kay until she started taking piano class on Saturday afternoon during 4th grade. FAST FORWARD TO OCTOBER 2015

Come Halloween MY SOGGF realizes  I was really enjoying being Tammie.  She said she was even having a great time doing my hair and makeup every morning b4 she left 4 work(I retired in 2015 to care for her) thus come morning after Halloween, she said Jammie you obviously like being Tammie every day, maybe u would like to continue living as Tammie thru my Firm's Formal New Year's Eve dinner and dance party.  I said okay honey I do like being Tammie and wearing feminine attire and makeup.  So I did including wearing a sexy Format evening gown for the NYE event.  Come new year's day SOGGF says how about we continue for the full year since I think U really are Tammie but trapped in a man's body is that how you feel? I said maybe so I've always enjoyed playing with girls rather than boys .. Yes let's continue. SOGGF says okay Tammie but then its time you get your own female attire and makeup etc. But FIRST YOU HAVE TO GET PROFESSIONALLY FITTED 4 YOUR OWN BRAS and panties at SOMA INTIMATES where I get my lingerie from.  Then Tammie should have her own Breast Forms  (SOGGF is  a double radical mastectomy BC survivor.. that's why I moved in with her late 2014 to be her at primary care giver after she returned home her surgery).

Thusly I've been living dressed fully feminine as Tammie with my SOGGF for nearly 4 and a half years, no longer have any mens attire. And even still had my mens attire I double I would be able to wear a mans shirt. Why my bust is 38DDD via way of my own breast forms attached to my chest with same waterproof surgical adhesive my SOGGF uses.

My  coworker is an extremely wonderful GG Lady an very attractive. She was extremely supportive of me when I had some serious medical issues in 1992. Thusly I TREASURE her friendship.  As she NEVER has known me as anything but JAMMIE and not seeing her since mid 2000s   my quandary and trepidation about having  lunch together again on the 16th of January.  And the how I as Tammie come out to this GG lady former coworker.

Part 1 of my trepidation

Should call my former coworker back  to  accept her INVITATION 4 LUNCH at noon on January 16th  & SURPRISE her by arriving dressed up fully ENFEMME as Tammie thus "come out in person" to her.

OR

PART TWO
Should call my former coworker back  &   "come out via phone" to her. Then if she indicates she wants to meet Tammie in person  Accept the invitation for lunch Also since I have many photos of Tammi should I email her a photo of Tammie,  then for lunch with her wear same outfit in the photo. Thus she will recognize Tammie if she arrives at restaurant before Tammie arrives.

Part 3

Should I gracefully decline for some reason.
