I don't know what to do

So lately my boyfriend and I have been having a load of problems and they're getting better but I still don't feel the same. It's been since July that these problems arose and has been a continuous streak. He's my best friend, and I really care about him but I don't know if we're going to last at this point. I find myself wanting to date other people or just be single but I know me and I love being in a relationship. I find myself annoyed at his immaturity and obnoxiousness. For example we'll be out and he'll see something and make a really, outstandingly rude or loud remark. We've been together 9 almost 10 months and I'd hate to end things.
