HELP!!!

Okay, so I know I said I wouldn't be on here anymore, but i need help so I thought it would be smart to get on Mibba. I need as much help as I can get. I'm not that good with these kind of things.
Anyways, it's my boyfriend. He is a pothead. I hate boys who do drugs! He and I are only in the sixth grade! It gets on my nerves A LOT! It's also kind of sad because they started this saying called "watch the house" and it was all because they were high. Talk about immature.
And secondly, he is a major pervert. I'm okay with being a little bit perverted, but every sentence is perverted to him. It get annoying after a while. This one time I was talking about the energy drink monster, and I was like "you know those big ones" and he obviously started busting out laughing. It took me a while to figure it out. After like two minutes i understood. All I thought was "woooooooow".
I have been thinking about breaking up with him, but I just don't know if I should. I want you to comment on this truthfully.
