My boyfriend made an extremely rude comment to me while I was naked...?

Ok, so, my boyfriend asked if I could do a strip tease for him one night so I did. While I was dancing for him, I was only wearing a thong, he told me my had a lot of cellulite on it and these were his exact words, "Damn, you gotta a lot of cellulite on your , what happened? never used to look like that" What he said... hurt me a lot because I never expected it. I'm not overweight, I'm 5'8" and 120 lbs.. but I do admit, I have a little bit of cellulite on my but I never thought it was that noticeable until he mentioned it. After he said that, my eyes teared up and then I ran into the bathroom. He said I was being too sensitive and he was laughing and jokingly called me a cry baby. He never apologized......What would you do if you were in my shoes?
