Things will get better in time, but it’s not your responsibility to resolve this

I’ve been best friends with Ellie [all names have been changed] for more than half my life. She’s truly one of the best friends I’ve ever had. I started dating Will three years ago, and we have a good relationship. Ellie was in a long-term relationship with Tim for five years, and for two of those years the four of us were a little friendship group. Six months ago, Ellie and Tim broke up, which really shook our group dynamic. Our larger, mixed-gender friendship circle has now split a bit into “boys v girls”. I still see Tim as he and Will are good friends, but it’s awkward.

The issue is that Tim has been confiding in Will about the breakup. Tim has a lot of anger towards Ellie and it’s causing Will to dislike her too. Ellie and Tim weren’t right for each other and probably should have broken up sooner. Ellie wasn’t a great girlfriend to Tim, but there was no cheating or abuse, just two people who didn’t work well together.
