I'm annoyed at my boyfriend.
Why are you annoyed at your boyfriend?
Because he's so immature. He's a slob and a mama's boy.
It seems that you are unhappy in your relationship, it's possible that you and your boyfriend are not a good match. You should talk to him about your concerns and determine whether it is best to keep the relationship going or to end it.
Shut the fuck up, my boyfriend is a good boyfriend and I love him. I'm just annoyed at these two things.
It's good that you're happy with him. Maybe you can talk to him sensitively about the issues you're annoyed with and, if possible, try to help him work on those flaws.
