I have been reading along, not really having anything to add as you navigate these new waters...until now.
Funny, you brought up the very thing I think about when it comes to (finally) dating again. I also noticed tendencies that I had that I just did not like. Things my xh didn't like, either, that I had brought right into a new situation.
For me, I wasn't really ready for any kind of relationship, so I picked someone emotionally unavailable..then repeated my life with my h, as I tried to get him to be more available. I guess old habits die hard. I see now that it was kind of my way of testing my own self-worth. Kinda dumb, since it was not a true test.
Anyway, I am glad you are seeing this so early on. Take your time. You deserve nothing but the best!
