Wow OP, guess I won't jump on the shared (and mutual) consensus that a relationship with this woman is an unwise decision.
I will however share a circumstance of mine. Cindy and I had a hurtful and immature relationship when we were just two dumb inexperienced kids. We said we were in love, in retrospect we were obsessed with each other, and no amount of agony, self-inflicted or otherwise, could change our minds.
Fast forward through a crushing breakup, failed attempts on both parts to woo the other, and finally, a year without contact. We met to exchange some old things and started dating again but this time, lo and behold, things were different. Not just better, but great! Easily one of the best relationships of my life.
Why? What was different?
Answer: 3 simple things. 1-We had both dated and not found the same desirable traits we sought in a partner. 2-We had matured considerably and learned a great deal about ourselves and how to keep a relationship healthy. 3-We BOTH wanted to be better, as individuals and as a couple, than we had been before.
Does your potential relationship have these 3 qualities? From what you say, I think no, but I don't know you, you tell me.
