I am sorry, sometimes I hate facing the truth, it just hurts too much.
All you can do is forgive yourself for making a bad decision, and keep moving forward.
Some people are not capable of loving themselves or another. This appears to be the case with him. People are just another commodity, a pawn.
Do something nice for yourself today, and thank god that you finallly had the sense to let him go, forever.
Hugs,
