I think I'm going to break up with my girlfriend.
Why do you want to break up with your girlfriend?
No particular reason, Just because I want to
Well, why do you want to? There always had to be a reason and sometimes it's a terrible one you'll regret later.
I don't know
Well you shouldn't just be ending a relationship for no reason right? You ought to think about this some more, and if you two are having problems you should talk it out.
