TITLE: My SO (19/f) just cut all contact from me (29/m)
POST: My SO and I have been together for about 6 weeks. No it hasn't been long, but that's besides the point. Last night we were at a small get together having a few drinks, when she randomly took my phone and started reading through my text messages (no this never happens. We actually agreed we would never do that to each other). She saw my ex texted me asking for her stuff back, and I said I would give it back to her. This happened a little around a month ago when we first started dating, and I haven't spoken to her since. She freaked out and told me to get away from her, and left.
A little off, but I also hooked up with two of her friends in the past, and she says she can't handle knowing I did this. It happened much before her and I were ever a thing. She told me "I know you're a good person. I'm just fucked." And that's the last I heard from her. She changed her relationship status on Facebook to single, and never even told me a thing. Am I wrong in this situation? Is there anything I should or shouldn't be doing?
TL;DR: 
my SO cut all contact with me in the past 24 hours, changed her relationship status to single without talking to me first, and I still haven't heard from her.
