Should I break up with him and how?

OK, if you feel you really love him and it would hurt more to leave then stay for a little longer, but you have to talk to him first and tell him. Give him time to change. If you see no change within 6 months then leave! I am going through a similar situation. I have been talking to him, and he will change for a little, but it seems like he ends up doing something else dumb to piss me off. I am giving him until the summer to get it together or else I'm chuckin up the "DUCES" I told him I can't take much more of feeling the way you make me feel. He said he doesn't want me to leave, so he is suppose to be working on it. So, you got to tell him exactly how you feel. Exactly what he does that makes you upset, and please use examples so he can see because guys can be really dumb! If he cares then he will change. Give him a time frame, but do not tell him about this. Just give yourself a time frame that you can deal with. I would say 3-6 months because change doesn't come over night, and you two haven't been together long. I hope it works out because it's hard leaving, but if you are more sad than happy, you may have to . I know its hard, but I may have to also. Be strong girl!!!
