Input: This problem has been plaguing me for months. I would really appreciate some feedback on my role in the situation as I am feeling deeply confused and sad. Sorry it's kind of long- I had to add a lot of details so the context could make sense. There is a TLDR at the bottom but it doesn't capture the nuance.

**Background**

My (F 30) best (?) friend, June (F 31), and I have been great friends for about 11 or 12 years. She got engaged to her boyfriend in late-2016 and everything was going great until she started getting cold feet in mid-2017. Once that started, she became very distant to her friends, would bail on our plans, wouldn't reply to messages, etc. My husband, Chad, and I have been married since 2015. My husband has this friend from high school- let's call him Zach. Chad and Zach were the best of friends during and in the years after high school and then kind of fell off of communicating after about 2007 when they moved to different states. We aren't close with June's bf/fiancé at all. He's a fine person, but not part of our regular group of friends. 

While June is getting cold feet, she strikes up a friendship with Zach that grows into an affair. During that time Chad and I reconnected with Zach and we all got really close. We have a ton of common interests and he's a great, attentive friend. Zach was really into June- he has genuine feelings for her and it seemed like June reciprocated. I thought they were going to get together for awhile. Long story short- June decides to break it off with Zach in early-2018 and go through with getting married to her fiancé about 8 months later. (btw: her fiancé knew all about it and they worked through it on their own and they seem happy now.) But Chad and I keep hanging out with Zach. June comes back to her friends but she's still kind of distant. I can tell that she doesn't like me hanging out with Zach but him and my husband are best friends- I can't avoid him so she seems to accept that. She doesn't ever directly confront me about this, by the way. She's pretty passive about these messages that I've inferred. 

**Current events #1**

Zach was also high school friends with some of mine and June's other friends and since he reconnected with us, they've gotten to be friends again, too. Right before the wedding in summer 2018- Zach and some of these other friends decided they wanted to party and catch up. We all decide to meet at mine and Chad's house because it's convenient and a fun space for a party. Obviously we didn't invite June- not that we were hiding it from her, we just didn't think it was necessary to run it by her. Well, she found out and confronted us. She got drunk and texted me a lot of hurtful things that night. I didn't respond at all and she apologized the next morning saying that she was too drunk and didn't mean it. She was mostly mad at me- not so much anyone else. We kind of talked it out but more so swept it under the rug and moved on. Things got better- I thought we were all in a good place again. My group of girlfriends were back to seeing each other regularly (June not so much, she's still kind of in and out but she's not as distant as before). We all manage to have a really fun time when we're together. 

**Current events #2**

Last weekend Zach invited me, Chad, and two of June's other friends to a concert and we all went. It was a really good time! But then June found out the next day and again got drunk and texted a bunch of confrontational messages to all of us. (Again, not trying to hide anything from her.) Some things she mentioned in the messages-- he was manipulative, he continues to be manipulative, he tried to ruin her relationship, he is trying to ruin her life. Now she isn't speaking to any of us. I texted her once asking to explain what she meant and to please talk to me. No word back yet- it's been about a day. 

**Am I the asshole?**

June seems to think so but I don't understand where she's coming from. I think she is being more of an asshole than anyone in this horrible situation. I don't expect her to *like* me or anyone else hanging out with Zach but I feel like she is 1) avoiding any personal responsibility she has in the situation, placing all of the onus on Zach, and 2) is being unreasonable by expecting me to drop Zach out of loyalty to her when she has been a fair-weather friend for the past couple of years. 

I've tried to keep this as objective as possible. If anyone wants additional info, just ask!

TLDR: friend cheated on her fiancé with another person who was accepted into the friend group during the cheating, expects everyone else to ostracize him since reconciling with her fiancé.
