Don't worry. Think about future and forget about past. Forgive and forget. You can't change it, so no point going back again and again.
Second lesson I have learnt is that anger is like poison. You drink it hoping for the other person to dye.
You can go to see a family specialist. Talk to her (I would prefer her over him, as he will not be able to help. He can't feel what women feels) and she will help you to get rid of the inside pressure. No one can make you happy- only you. Just like that- out of blue moon- you are happy and there is nothing anyone can do about it. Once you are happy and shine, love will come again. Just don't open your heart too much.

Good luck
