It’s the trust part that is difficult to get over. Some stay single and continue working on themselves, and that really is the only path in my opinion. Can’t have a decent relationship without trust (both parties). Any trust issues unresolved will just end badly in a new relationship, since the new relationship isn’t starting on the right foot to begin with. Some tend to think that the trust issue can be resolved by bringing someone else into their life as a “solution”, and in the longshot of a perfect pairing between two people it may work for a bit, but the chances are real slim.
I’d love to find a “lifetime” disney movie worthy relationship, but like you, I’ve chosen to remain single at this time in my life, and just enjoying the flexibility and ability and time to really get to know who I am and strengthen everything I’ve learned along the way.
