Break up or Not

I’m honestly not too sure I should break up with my boyfriend or not we’ve been together for a year now but I’m not sure if I should because don’t get me wrong like he treats me amazing. He’s the best guy I’ve ever been with. We can communicate. I’ve never been able to do that in a relationship before, but honestly, some of the things he does just infuriates me And it’s not just me. I also have a 16 month old daughter who he has just admitted saying if he’s not sure he’s ready to be a step father or not. Like he smokes weed which cool I’m OK with but sometimes he smokes to the point where he’s like nodding out. He’s stumbling almost falling over just you know. Keeps me up late at night when I’m trying to sleep because he spends the night here sometimes like it’s just so annoying when he does that because I have to get up in the morning with my daughter he also makes my room a disaster zone when he’s here which also makes me so angry because then I have to spend time cleaning when he leaves so I’m honestly just not too sure whether I should break up with him or not like he’s a great guy all in all but I think we just clash sometimes I just need some opinions. Thank you.
