TITLE: [M/F early/mid 20s] Boyfriend insults me quite a lot (jokingly says I'm dumb, etc). Not sure if this is a problem or not.
POST: Hey, so here's the deal. My boyfriend and I generally have a good relationship. We never really fought about anything, except maybe once or twice over the course of half a year (the part I'm about to explain).  However, there is something that has been bothering me quite a bit, and I am not sure if this is an actual problem, or just me being hyper-sensitive.  He tends to insult quite me a lot, but he doesn't (seem) to intend to, and if so, in a joking kind of way.  He would say things like "why are you so stupid?" or "why do I have to do all the thinking for you?" and such.  He does think highly of himself, which doesn't bother me.  It's when he says these things that bothers me.  I've talked about him about this a few times before, but this hasn't really solved anything.  The conversation would just end in him saying that he either doesn't remember what he said, or that I just took it the wrong way and it was a joke.  He never apologized about it.  After a while, I tried to just ignore it, but it still really bothers me and I'm not really sure what to do at this point.
TL;DR: 
Boyfriend is a nice guy, but insults me a lot and I'm not sure if this is a problem or not.  Talking about it didn't help.  Looking for advice.
