I don't know if I should break up with my boyfriend of 2 years

I have been dating my boyfriend for 2 years and am suddenly feeling very unsatisfied. I don't know what to do either. I love being around him and I truly do love him. But starting in like August I started having dreams that I was cheating on him or breaking up with him and feeling extremely relieved about breaking up with him in my dreams. Then I would wake up feeling so confused about my feelings. Then this Christmas he was very disappointing, he did nothing for me until I got really mad at him and then he did something very thoughtful. To be honest, I told him he didn't have to get me anything but I at least expected to get a card. Then, I had a massive dinner party on new years for everyone and instead of helping me, he slept the whole time. I'm kind of getting the urge to be free but he is also my best friend and I truly do love him. I just think he's so immature because I am his first girlfriend ever and he is my 5th long term boyfriend. He's an incredibly kind, generous, smart, and intelligent person. I dont want to make the wrong decision but I am just super confused and have been for a while now. The worst thing is is that we are signed up for a dance class that goes until March. His dog just died. And his Christmas present he got me is not for a month. What do I do?

Well personally as a guy I can relate to him just kind of wanting to sleep. Its normal for a guy to get kind of lazy when he gets comfortable with you. Im willing to guess that he didnt automatically start being lazy all at once. It just gets easy to sit around and if you really love him you need to help him work out of it. we guys get lazy start small and get him back into gear. my last girlfriend got me into that same rut by making it easy on me to do nothing andshe was ok with it at the beginning then all of a sudden she notices and gets mad. Dont get mad help him if your willing to other wise leave him. but let me tell you all guys will revert to a lazy state if you make it easy.
