I feel that I complain too much to my SO

So awhile ago when I wasn't dating him, I asked my boyfriend if I was dramatic. Granted he was my best friend and I could always count on his honesty. He said yes. Fast forward to now and I am always overly conscious about how dramatic I may be being. I know I probably complain to him way too much. Every uncomfortable thought that goes through my head gets told to him and I just feel like he doesn't want to hear it. And I get it, if he was constantly complaining to me then I would get tired of it too. He says I don't complain too much but he's probably just saying that because he's my boyfriend and doesn't want to hurt my feelings by saying yes I do complain too much. I sort of actually really hate myself for it. Like I want to tell him everything because I don't have other friends to tell and I don't just want to keep it all bottled up. I just feel so annoying. :/
