x boyfreind infanate chance

Yes it is stupid to give unlimited chances. If you give someone a next change this should be under certain conditions and with the idea it will work this time since both are willing to make it work. I also doubt if these unlimited chances are really given out of love or if it's more the fear that nobody will ever love you again. These kind of man are great in making you believe that and blaming you for what they do. If he doesn't know what he wants it's surely not you otherwise he would know that. So this sounds more like a place to turn back to if I have nobody else. Unless you like to be humilated and kicked down and stabbed in the back and be laughed at you should not start a relationship with a person like that. By hanging in and hoping for better (which will never happen) you are only wasting your life and good years and take away your chance to find someone who really loves and appreciates you.I think that is a big shame.

There's only so many chances he can have. It would take it's toll on you eventually, and one of you have to break the cycle at some stage. So you both can get the best out of life.
