Most Helpful Guy
Maybe overreacting, I have a sister my age who had this trouble and I can tell you maybe you want a lot of attention. He may or may not had his reasons to not answer you but if youve been that way lately, maybe he doesn't answer you cause he is getting tired of that attiuted. You are being possessive.
Or maybe he is being an asswhole and puts you at the end of he's priorities, I don't know you neither your boyfriend, I can't tell you which case it is but I see things aren't working between you two.
Take it easy and talk to him about it if you haven't done that. If you already had well then end up the relationship cause its making you bad.
