I can tell that you had a passionate relationship with this woman, but I could not help but focus on the part where she physically abused you and (could have) almost ruined your reputation by calling the police on you, though you did not do anything wrong. Maybe she was afraid of who she becomes around you (not your fault) and therefore needed to start anew. Whether you are sober or not, maybe she felt that she couldn't remain sober and in a healing state in the relationship - maybe even too much damage has been done. It hurts a lot when relationships end, but more self-love and distance will make you see that it was for the best.
