am I a doormat?

[psusensei]

Ok, so my boyfriend turned 21 last night, and of course got completely trashed. I didn't go because I am not 21, but he and his friends thought it was a great idea for him to come to my apartment after the bar so he could recover there and puke if need be without freaking his parents out. Well, I drove all the way out to get him, and drove him back to my place all the while he is cursing me one second, about to cry the next. So ALL night I am up in the bathroom helping him, washing his face, rubbing his back and cleaning him up after he throws up. I had to clean thr bathroom at 2 am so my roommate would not be grossed out, and I had to sleep on the floor because he was sprawled out and I couldn't move him at all. Then he wakes up feeling fine, and immediatley calls his friends to find out the funny shit he did that he did not remember. He doesnt remember me helping him, doesnt even remember throwing up, so of course there is not even a "thanks" this am. Lastly, I spent the whole weekend letting him use my car to drive across three states to hang out with his friends...with nothing but complaints from him about how my car sucks. At this point, I feel like a total tool, like I am being taken for granted. Am I his personal doormat? He and I are in love, and he tells me often, but I feel like my opinion, my feelings, my actions don't mean jack shit to him anymore. What gives?!?!
