Does this make me an a**hole?

So I saw my ex for the first time in a year on the bus the other day, and she must have gained about 40 pounds since we broke up. This made me feel great because she was sexy as hell when I was dating her. She said hi and I mentioned that the purple sweater she had on made her look like grimace from the McDonals gang. hahaha. Am i a dick or what?
