DarkAng3L, I'll just give you a few of my thoughts for now.
You keep dating this man and you keep breaking up with him.
This tells me that there is something between you that could be good and strong, but that there are also problems, which are not being dealt with.
If you are to stay together then these issues need to be discovered and addressed.
You mention him being sarcastic, and making you cry. Is he actually a good person?
Are you talking about arguments and disagreements, or could he be violent and abusive?
Is it true that he doesn't believe you, about simply helping out this other man?
This is something that you need to consider very seriously.
You ask about breaking up with him, but if he has had nothing to do with you for at least two weeks, after being sarcastic and unpleasant to you, then it sounds as if you already have broken up.
Do you want to pursue him?
You say you love him, but it doesn't sound like a healthy relationship.
Have you got someonme to talk to and get support from ~ family or close friends ~ while you try to sort yourself out?
You have got back together before, so maybe you will again, but think about the pattern of this relationship and whether it is what you really want.
If you do, and he does, then I would suggest relationship counselling.
