I want to breakup.. but

We clicked so perfectly in the beginning, then we started dating. Things were going good, I love his mom, his family everything. Like a lot but him, not so much honestly. I mean, it's a rollercoaster honestly. The arguments don't even be about us, mainly because he always brings his friend around when I mainly want to spend time with just him.... honestly I think if it wasn't for the sex, or if we wouldn't have had se, I wouldn't be with him.  
 I honestly can't finish this message, I just started crying cause this is so Deja Vu, with my last relationship,  how you want everything to workout but you just don't even know how, my moods just change up so quick. He's just always doing annoying stupid stuff, no matter how much I repeat myself. I'm having so many emotions right now.
