Should I Wait?

Well this is a follow up of some sort, my boyfriend has been going through a rough family time, he has always had a bad relationship with his parents anyhow. He claimed he wants a break, but then he started to date someone else two days later, he says he still loves me and wants to get back together after a month. I don't know if I should be okay with this, he has hurt me so bad, but i know his life style too and how he has been living.Yet it still doesn't give him a free card to hurt me as he has. Should I wait or should I cut my losses? Actions speak louder than words, and he knows how to manipulate people to get what he wants, but he also is very indecisive and listens to others instead of what his heart and mind tells him...There are half that says wait, and then there are others that are shocked he could, let alone would do something as he has. What to do?
