There was a night where one of my roommates got drunk and for once I didn’t. We were all having a blast except for two times she made rude comments about my mental health but I brushed it off. The next day she came at me asking why I was so rude and angry and mean to her the night before. My other roommates and I were extremely confused as none of that was true. I mentioned that the only time I may have seemed a bit mad was when she made the two comments but that I didn’t actually care. She flipped, stormed out of the apartment and I left the apartment. I wrote her a huge note apologizing for her misunderstanding my mood and whatever else I had subconsciously done (since I had a great night and didn’t think I was mad at all). She denied saying anything about my mental health and never apologized for flipping out on me even though the roommates also backed me up. We haven’t talked in 5 days. We live together and share a room together. However I did my part - I wrote a letter apologizing, I told her over text that I was sorry, but she hasn’t yet apologized for anything she’s done. I feel as though I shouldn’t be the one to start the conversation/ grovel at her feet since I already apologized and everything. I don’t know what to do but I feel like a shitty friend even though I shouldn’t feel like a shitty friend. Advice?
