How to deal witha Breakup?

Someone tell me, I was with a man for 3 years we lived together, worked together you name it we did it. People even knew us as a married couple. There were a few occassions where we had infidelity issues but nothing major, I forgave him we moved on, but then before we went on vacation he cheated in another city with a woman he barely knew? Now after 2 months I still miss him, and he is moving on as if I never exsisted? He has called and acted like we are friends expressed that is what he wants for now, that he is not ready to be with anyone right now. I have on 2 seperate occasions asked him respectfully not to call me anymore that we have nothing to say anymore. But just recently I have had to yell at him and curse to tell him not to call me anymore, now 2 weeks later no more calls. But why cannot he not see what he is missing in me? Will he never come back? Please help?How to deal witha Breakup?
First off you need to MOVE ON!!! He obviously doesn't respect you enough to stay faithful, he may come back if you continue to act like his lap dog that lets him get away with murder, desperation is not attractive!!!!How to deal witha Breakup?
Well as for why he might not come back, you did just yell at him. But I have a little experience, unfortunately in the cheating department. Sometimes there is more to it then people see, and although it is the cheaters fault, it wasn't planned by the cheater to happen. I think that he probably really regrets hurting you and that he's afraid that if he gets back together with you, it could happen again. I'm not sure what he's like, but I don't think that most people can throw away 3 years without batting an eye. If you really want him back, then forgive him and maybe apologize for being so short with him. Everything you feel about him, just tell him. Even though it hurt that he cheated on you, you still feel for him. If you tell him everything in your heart and he still doesn't want you, then you two were not meant to be together, and you can try and find someone better. There are many people out there and you seem capable of finding someone good for you.
