how do i break up with a psycho g/f????

I think its part of becoming a man to have a mandatory crazy to deal with. They way i got rid of mine, was became the worst guy possible, was rude as hell, would lay out a big fart while “cuddling” belch her name when i wanted her. any thing that would be funny to guys is disgusting to them. they become repulsed by you and finally leave. Then about a year and a half later ask why.
