Hey. Quick check in after the party--started early, ended early.
I would not apologize but tell her that you noticed she's been distant and have been wondering if it's bc of the way you reacted. Then if she says yes, I would try to explain how you're going through the process of trusting her again, and how it'll take time. Make sure she doesn't feel as though she's the bad person. Guilt should never be induced by you. Bottom line, definitely bring it up. At least that's my take. I hope I'm right :-)
