Gf got SA

TLDR: (English not first language sorry and new to reddit) It was recently revealed to me (23M) that my gf of 3 years (23F) was raped. We do not live together. She is an artist for a living and recently she had been very avoidant (I have anxious attachment). For a couple of weeks we have been distant and arguing (I was oblivious of SA incident until now). In September,she went to an interview to a studio and she told me at the time that it went horribly with not much elaboration. Today, she told me, with hesitation, that the business owner raped her upon interview to coerce her in to returning (quote from her: “come back tmrrw for a plan B”). He knowingly impregnated her and she had to get an abortion and file a police report, of which I had no knowledge of. I have no idea what to do. I am a mess, as a student in the last semester of nursing school and a recovering alcoholic, I have no idea how to help or what to do. So many thoughts are racing through my head. Has any one gone through a situation like this? What did you do?
