You would need to present evidence that they assaulted you and that you did not commit any violations of the law. Unfortunately for you, going to her house will work against you in this case and you will have to come up with a good reason as to why you went ther and "bother you" will not suffice. You would need a legitimate reason for the visit and you will also need to prove you took no action to warrant the assault by the friend and boyfriend (and making fun of you would not be good to say either). At this point, I strongly urge you to hire an attorney to represent you in this matter.
