I'm sick of this crap. I'm just going to take off and leave my date behind
What is wrong with your date?
I only want to go out with guys who are mature enough and don't break up with me the next morning
It's rude and inappropriate to suddenly leave someone behind on a date, but if the date isn't going well, talk to them and let them know how you are feeling.
Whatever. I'm leaving anyway.
I think you should at least talk to him. When he finds out he's been abandoned he's going to feel hurt. I think you should give him some kind of explanation.
