Hello Jadek, I know because of my Domestic Violence work that an ex is an ex for a reason. Most likely people don't change. It only sets up for a lot of heart ache in the end. You can't change someone. They are the only ones capable of doing it. You have survived for a year without him. I imagine it has been difficult. A lot of womyn think they can not survive on their own. But you can. I am not saying your case is of Domestic Violence, but the criteria is often the same. Just be careful.... good luck with what ever decision you make.
PM me if you would like.
