Need advice

Long story short, my fiancé and I haven’t had sex in almost 2 weeks which is very out of the ordinary. The last time we did it was just a quicky. He’s not even acted interested, I finally shoved my titties in his face last night but still nothing. He watches porn and has been quite a bit, even when I’m fully accessible and more than willing. The porn he watches is older women in the “chubby” category with big titties. I’ve got a bit of a tummy but not enough to where I’d be put in that category, I’m younger than him and I’m a B cup. I can’t help but feel insecure but I know if I try to talk about it he’ll try to make me seem crazy for bringing it up. Am I overthinking it?
