Input: This requires a bit of context but I'll try my best lol. There's two friends here, I'll call them Rachel and Lily. Rachel has been one of my best friends since sophomore year in HS and Lily and I became pretty good friends senior year, but those two were super close too. These friendships carried on into college and they met some new friends with people on their floors and this group of 10ish girls would party together, go to football games together, etc. This group includes Rachel's roommate.

After a night of partying, Rachel was going to one of the girls' dorms where they were all were. (Rachel stayed out later). She opened the door, and out of nowhere, one girl started going off on her while everyone else, including Lily and Rachel's roomie, just sat back in silence and let it happen. The girl accused her of "shit talking" everyone (it was like tiny complaints that aren't worth making a big deal over) and exiled her from the friend group. Rachel was hurt that no one had talked to her reasonably before humiliating her in front of everyone while she was drunk and couldn't comprehend the situation.

Rachel was the most upset about Lily who was her best friend out of all of them. Lily is the one who Rachel would go to when she had complaints about someone, meaning it was her who ratted her out. After all of that, Rachel texted Lily who said she didn't want to be friends anymore. She and the group of girls continued to shit talk Rachel and made her feel horrible.

I was there for Rachel, took her side, and supported her whenever she wanted to rant. I'm not a confrontational person so I didn't call Lily out but I made it a point to keep my distance from her. Rachel's roommate still remains super close friends with Lily. There are also friends of ours who have stayed close with Lily and while it makes her upset, she never calls them out.

Fast forward to a few days ago, all the drama happened 4 months ago, which is the last time I had spoken to Lily. I was at Starbucks doing homework and I got up and I see someone waving at me, it's Lily. She's a very enthusiastic, high energy person so she goes "Hi I haven't seen you in forever I miss you so much I love you!!!!!" I'm the type of person to match people's energies (if that makes sense) so I go "omg hi!!!" I give her a hug, compliment her hat, and then carry on. The interaction lasted 10 seconds. I felt weird being nice to her but would feel even worse if I ignored her or was mean when she acted so excited to see me.

I thought that was the end of it, but Rachel's roomie told Rachel about the interaction and now Rachel won't talk to me. The only reason I know she is upset with me is because she keeps posting passive aggressive things on her finsta story about being upset with someone and I wasn't invited out with her and our friends last night so I'm putting the pieces together myself.

Am I the Asshole?
