no kneecap can resist a steel pipe

Leave girl you are to immature to ever love her again

save time. beat the shit out of her.

Get a roll of quarters and hold them in your fist when you sock 'em.
Or get a gun, if he comes in your house you can shoot him in self defense, open and shut case.

also don't use her phone to invite him over thats how you get caught. just go find him out one day or wait for him in his house

using a weapon seems a bit beta.

?
explain..

depends on the state also if he's invited its not

Kill him, then your girlfriend, then yourself.

Improve the world a little bit.
