<human>: So I'm about 20-25 pounds overweight. Have been my whole life. I think I'm attractive and I'm confident even though it took me a little while to get to where I am now. Of course there are things I want to change about my body but I also love it.

I was this weight when I met my boyfriend. He's incredibly thin, always has been, bordering on underweight. Though that's not normally my type, I immediately loved being around him and that made me attracted to him. I still am, or at least was until this happened.

It started with questions about where I'd eaten lunch that day. I normally eat out at work, I'm getting a PhD and graduate school takes away from the time I have to cook for myself. I thought he was just asking because he was interested in my day but it quickly became "ugh that's so unhealthy". Yeah, you're right, that bacon cheeseburger with chipotle sauce WAS unhealthy but why do you care??? When you have literally never cared before???

Eventually he approached me and said that he felt I needed to lose weight. He tried to say it was for health reasons but I assured him that all of my bloodwork and cholesterol levels and blood pressure are always great and I've never had a doctor tell me I need to lose weight. If they do, I'll work at it but right now I like my lifestyle. I'm in fucking graduate school, I really don't have the energy to even THINK about my weight. I pressed him and he said I'm not attractive. Not that he doesn't find me attractive but that I'm not attractive in general. I left his apartment immediately and haven't even looked at my phone since.

We've been together for 3 years. Our sex life has been great. He's always told me I'm beautiful. Where do I even go from here?

I'm too embarrassed to talk about this with my friends and family. Typing that out made me realize I'm feeling ashamed about my body right now which I have not felt in literally years. Ugh.

Can you provide a brief rundown of the text in within 3 sentences?
<bot>: Boyfriend suddenly wants me to lose weight after 3 years together. What do I do? What should I say to him? I'm feeling lost.
