Well I'm glad you guys were right; class went fine, no awkward vibes. It ran pretty short and we were in seperate groups, so I didn't get a chance to talk to her, but afterwards she texted me. Apparently she thinks our professor thinks her and her (female) friend are dating because of how close they are, so she texted me afterwards and said that they finally made it clear that they aren't. Which kind of sucks because half the fun of that class was watching the professor interact with them and trying to pick out all the indications that she thought that.
But that's not really relevant. I actually wanted to post in here and thank you guys. I know I've been a PAIN. IN. THE. ASS. for the last 3 weeks, but you all helped me a lot. I feel a lot better about myself now that I don't have this thing hanging over my head, and it's nice to know that she knows how I feel and (at the very least) isn't running away screaming. I'm really glad you all pushed me to do it and were so nice about it, even though I kind of shitted up the thread and drove you all nuts in the process. So thanks, it means a lot.
Also, every time someone in here cracks a joke about the "Matty saga", I can't stop laughing.
