Pink, he can't make you happy...no one can do that but you. You have can have a great life with or without him. You have to. What if he had died? Would you be able to go on? Yes, you would have found a way to eventually move on. Right now you are grieving and that takes time. But, you WILL be ok.
As far as the resentment, the only person that hurts is you. It eats you up inside, it keeps you from having healthy relationships with other people. I think it is a decision to let go of the resentment and forgive. Do it for yourself. Do it for your daughter.
