I have no idea what to do about my boyfriend.
What about your boyfriend makes you not know what to do?
I just don't want to hear his complaining is all.
That's understandable. Communication is key in a relationship, though. You need to tell him that you're tired of the complaining.
Nah, I'm going to cheat on him.
It's healthy to talk out your differences with your partner so that nothing is left unsaid, which can cause trust issues and drama.
