Is It In Anyway Illegal To Keep Riding Past Someones House?

This is the quick story......My boyfriend cheated on me with this teenage *****......He has stopped seeing her and we're trying to work things out. I smoke and I go outside (because I have a 9 year old son with cerebral palsy and I don't think he should be around my smoke....), and her friend keeps driving past my house! I don't know if the skank he slept with is in the car or not. But last night she rode past my house 6 times!!!! And she yells sh*t out the window and plays music really loud. I didn't do anything to these people except call the skank a .....(cuz that's what she is....) I'm tired of this crap!!! And I think a couple of times they have threw things at my car and house (a water bottle & a big bolt). This is so stupid!!! I'm 29 years old and I really just wanna punch these bitches in the damn face!!! But I have never been in a fight in my life. I just don't know how to get these f-ing teenagers (they are 19) to STOP driving past my house!! I'm tired of this CRAP!!!
