firstly,i want to ask you one question:have you ever talk to him all about these quetions?is him willing to change himself?
secondly,i want to tell you:in fact,no one can tell you what to do.love should never be mastered by others.i think you what you should do is to ask yourself what you want,which kind of men you want,and can you tolerate all these weaknesses he has,is he really the one you want.if your answer is negetive,and he also does not want to change himself,just leave him.
finally,love is built on the efforts of both and problems may exist everywhere you two should both have the preparation and determination to solve it together.good luck to you!
