im scared😢😭😔

me and my boyfriend have been together for 10 months and it just doesnt feel the same anymore. whenever i try to start a conversation he just dry texts me. it makes me feel like im being annoying, but whenever i ask him if i am, he says no. and i always try to mention how much i miss him since im in florida right now and all he says is miss you too or same. he always used to call me cute names like baby or babe but he never does anymore. and sometimes he doesnt text me at all and i dont know why but it worries me. i love him so much and i definitely dont want to break up but i just dont know if he feels the same way about me. he says he does but i dont think so. please help me as im scared to lose him.
