I'm ready to go. I'm done waiting on my girlfriend
Wait, are you seriously thinking of just leaving her? Why would you refuse to wait for your girlfriend?
I don't see it necessary to wait for someone who takes so long.
You should wait for your girlfriend especially if you love her. I doubt she is taking a long time on purpose anyway, and you not waiting for her is going to give you more problems than leaving early to save time.
Whatever. I'm leaving her.
You shouldn't just leave. Instead go tell her you're ready and ask if she's riding with you. She will be really upset to learn that you just abandoned her.
