Dude on Tinder 🔥

Okay so this guy I match with on Tinder and I have been talking for almost a week. We we've been talking every night and he was someone i just like to talk to nothing serious. Well we were on the phone last night and we're talking and he asked what a wanted with my future.. then he says with your body I mean. (Yes I am a big girl but I never hid that. I have full body pics up and its connect ro my IG so he can see other pics of me. I dont hid the fact I am big) And I was a little confused.. And he goes on this tangent about people in his family being overweight and being in wheelchairs and having these diseases from being overweight and he said that if we were to pursue a long-term relationship he would want me to lose weight cuz I'm fat and at risk for diseases because of that... I do understand where hes coming from I guess idk. Am I overreacting??
