Does my boyfriend love me? Asking a more mature audience :)?

My boyfriend and I got in a fight last night... Not sure if he meant what he was saying... But anyways... I accused him of posting on his twitter "why doesn't the dmv hire some more hotties if we have to stay there so long" (he does have a dry sense of humor but it sort of made me mad).. He got defensive and started going off on me saying I was a "dumbsh**" and an idiot and retarted... I told him dont call me those things it's so disrespectful and it's pissing me off.. He said well you have such a thick skull its hard for me to get through to you... He said I don't get him and what not... Which idky he said that he just kept going on and on.. Then he brought up his ex gf's when all I was saying then just explain it to me(he said I shouldn't have to you should just get it by now) and don't call me those names.. He said he feels like he's walking on egg shells with me.. which idk don't think he does he shouldn't call me those things and if I feel something isn't right I am going to say something... His stories come so scattered and from time to time change just for the good of him to prove a point in the situation or argument we are in...He told me if I do something like this again we're done... I said don't threaten me like that..He said it wasn't a threat its a promise... Does he still love me... Did I do anything.. Is there something wrong with me??
