Ouch, f*ck... It's a sticky situation, ain't it? I feel ya. At least if this so-called "legal stuff" that you got in trouble for was not something immoral, anyway. Like, if it was a drug violation..? You've got my sympathies, 100%. Arbitrary, bullsh*tty f*cking laws that they are. Just.. I have some idea who you *might* be. Or who I suspect you *could* be. Although of course I could definitely be wrong about that.
Anyway... She's not worth your rage. Speaking as someone who also struggles with a lot of anger sometimes..? It ultimately only hurts YOU, more so than it could possibly hurt anyone else. Same with resentment.. I've just been through a period of feeling SERIOUSLY f*cking resentful about something, and it's been awful. I'm exceedingly freaking glad that I've almost managed to let go of it now! It's like a HUGE weight off my shoulders.
Maybe just let her know that you know what she did. Cut all ties with her, if you guys are currently in touch. Although I'm guessing you probably aren't.. Obviously, if she wants to judge you for something stupid and petty like that, she is NOT your kind of person. And also..? There are other meetup groups. And other people. Plus if what you did, that got you in trouble with the law, was NOT immoral..? Probably many other people in that social circle will still be willing to stay in touch with you, anyway. I know I would have. Just.. you need to hit them up, and present your side of the story.
Best of luck. And.. I wish you well. :)
