I'm going to throw my girlfriend out of my apartment.
Why would you throw your girlfriend out of your apartment?
My sister told me that my girlfriend is unhappy with me and I think she's right.
I know you're upset, but you shouldn't just kick her out. You need to have a conversation with her first.
I don't think speaking to her will do any good, our relationship is over.
If you talk to her you probably could work out your issues and not end the relationship. You should give it a try instead of just throwing her out, that seems very cruel.
