Denver, what a rough couple of days man. Sorry you're going through all of this. I could be wrong, and others may correct me, but seems odd that she continues to engage in this. If she were really wanting to be "done" seems like she would just disappear. Not sure what that means, or what you want to do with it....but is OM really 19 years old? That might be fun but not really good prospects for a long term, stable R.
Also, sort of think cat04 has a point - you may some justifications for going to visit her house, which have some logic, but really you went there to have this confrontation with OM, right?
