Dreams about me and my boyfriend breaking up?

we've been dating for almost 2 years, were best friends, and we have alot of fights but we eventually get over them, but we mainly fight about him looking at other girls, hes stopped majorly since i first caught him and he no longer looks because he wants to, he'll tend to look because the girl is right in front of him in a bikini. but the problem is that i constantly have dreams that i break up with him over this when i dont want to break up with him, the thought enters my mind occasionally but ONLY when were fighting intensely, never just because im thinking about ending it. can someone tell me what these dreams mean??
