Should you stay with a man who has issues from his past and brings them up?
It’s hard when he compares you with his ex and accuses you of things you did not do just because he still lives in the past. I would dump him.
It’s not a good thing to be in a relationship with that kind of man because he’s going to make your life a living hell.
If you always remind him that you are the same girl he initially loved, it would work. This would help the guy heal by showing him that he is loved.
