I've only had one boyfriend, but I got mad at him almost daily, (that's why he's my ex now ;D). Just start a normal conversation and don't say "we need to talk". That's just a stupid cliche line. Just talk to him how you normally would, and then tell him,"When you said/did _________ the other day that really pissed me off >:(". That's what I would do. I had to tell my ex that all the time. Of course all he said was sorry...but this is about you! So just don't blow up on him, and I'm not sure how many times he's done this before, or how close you guys actually are, but I think that you should just try to talk to him about it, and avoid fighting at all costs. If he seems to go on the offensive quickly, try apologizing too (that is, if he does). Just don't fight, because no one likes to fight with their boyfriend/girlfriend.
