What is the name of a movie where the boy trys to break in his ex-girlfriends house?

Hey guys I've watched a movie a long time ago but I cant remember the
name of it.
But I remember that the boy has problems with his girlfriend's
father... soo he hurts himself and tells the girl it was her father...

I also remember that one night the girl gives her boyfriend the
password to her house...
and later on in the movie he tries to break in with some friends...
Does anyone know the name of the movie?? Thankk youu
