Please help, I don't know what to do?

You dont sound very happy at the moment, but I suppose if you break up with him and then realise you miss him he may not take you back. Could you try another option? Develop more of a life of your own and spend more time with your own friends. Even make new friends. If there are things you enjoyed doing before you started seeing him, start doing them again. I dont mean refuse to go out with him, just dont be always available, and have a life of your own. Either he'll realise that he's got a really good thing with you, and start to be more attentive, or he'll not care, in which case you know you would be better off without him.
