Help with my boyfriend? no mean answers please?

my boyfriend and i have been together for 10 months, no doubt its been really good, im his first girlfriend and he has never been happier, even when we fight he is super happy to have me around. even if im not talking to him. but.. i think its me that has the problem. i dont know if im happy anymore... there is NOT another guy or anything like that. i just dont feel happy. i mean we are ALWAYS together, every single day, i mean even when i was just on vacation out of state for the week, he would text me EVERY DAY and call me every day. so i feel like i didnt really have a vacation cuz i mean i thought that would be my break from seeing him and talking to him, and when we talked about it he said " i talked to you everyday when i was on vacation" well yes he did but that was HIS choice, not mine. i feel like im being suffocated, and EXTREMELY tied down and i dont like the feeling. so i dont know what i should do, if we should just call it quits or what cuz he is just so happy and im not... any help please? :(
