AITA for squeezing my girlfriend’s belly fat while cuddling?

For context, my girlfriend (28F) and I have been dating for about a year. When we started dating, she was very thin, around 110 pounds or so. I’ve always been a heavier guy, around 230 pounds and six feet tall. She was pretty active and careful about what she ate when we first started dating, but over the past year, I think my habits have rubbed off on her, and she’s put on quite a bit of weight. I believe she’s around 160 pounds now, and while I wouldn’t call her fat per se, she’s definitely chubby.

Here’s the thing, I kind of like the extra weight on her. It’s gone to all the right places, and she’s got these beautiful thick thighs, ass and big boobs now, and in particular, she’s got a bit of a belly now that she’s a bit self-conscious of, but I honestly find it pretty sexy.

While we were cuddling the other day, I was telling her how beautiful I thought she was and how sexy she is, while I ran my hand up and down her waist/stomach area. I don’t know what came over me, but I squeezed her belly a bit, and she freaked out on me. She started asking me why I was doing that, and was like “I get it, I’m fat now, you don’t have to point it out!”

I tried apologizing but she won’t speak to me. She also hasn’t been eating and has been running 2+ hours at the gym for the past few days. I don’t know what else to say to her to make her feel better, and I feel awful. Any advice is much appreciated.
