Should I ask my boyfriend to leave?
Maybe. Why are you asking him to leave?
He's not treating me well right now, so I want him to leave.
It's fine to ask someone to leave if it's for a good reason. Otherwise you might feel unsafe.
I'll be fine. I'm sick of his shit.
I am sorry that you are so upset. Ask him to leave if it will make you feel better or if you just want him gone. It is your prerogative.
