boy trouble?

so i'm a freshman in high school and talking to this guy for about a month and i really like him like a lot. i miss him all time and we text all day and all night. but that was at the beginning now we rarely text or talk in school. but he still calls me beautiful and baby and babe all the time. hes constantly telling me how much he likes me. ive sent him nudes and last week we had a fight about it. i said that i feel like he only likes me because of my ass and how ive done stuff with guys. his response was that that pissed him off because hes never ask me to do anything or send him stuff. lately ive felt like his feelings have changed and that he doesnt want to talk anymore so i feel like i should end it but i have know idea what to do. of course i really like him and dont want to hurt him. i guess my question is what would you girls do if you were in my shoes?
