How do I convince someone, I'm not in love anymore ?

Her- Just don't be around ?
Me- No, that can't happen. I'm always there. Even for strangers, come on. I'm weird. :( I want everything at the same time, and not want to get hurt too, is that even possible ?
Her- No, it's not.
Me- See, I have to let this person know, and I don't even want to be rude.
Her- Hahahahahahahahahaha, all the best. :)
