Do I hang out with my boyfriend too much?

Yes, I'm going to be honest with you and say you do hang out with your boyfriend a LOT. It sounds like a great relationship, and I'm glad you're so happy with it. Just don't let him take over your life. Spend time with friends too. They'll stick with you just as long and maybe longer than him. If you break up with this guy, they're the ones you're gonna need to lean back on. Just be aware that you have a life of your own outside of him.
