Bit of an odd situation here but will try and explain the best I can...
My husband and I have been friends with a Guy, call him Tom for a long time. He was friends with DH first but I've also been good friends with him now since I met DH. He had a long term partner, Chloe, for a number of years and they have children together.
Me and Chloe are quite different and I don't think outside of my friendship with Tom I would have really ever known her or had a friendship with her but over the years we have maintained a semi friendship due to mine and DHs friendship with Tom and we used to get together quite a bit when they were together. I haven't liked the way she treated Tom in the past (jealous and a bit controlling imo, demanding he block women on SM, reading his messages and so on).
Anyway, Tom and Chloe split up earlier this year. I stayed in sort of contact with Chloe to be polite but we don't speak a great deal anymore.
I have a very good friend who was also newly single, Sarah. Her and Tom had met before but more recently in the last few months they have been dating. I'm really happy for them as I love them both 🙂 me DH, Tom and Sarah have been going out as well and doing things together (recently went to a festival together, that sort of thing).
Anyway, Chloe has messaged me about how hurt she is about this and how I'm supposed to be her friend and she feels betrayed.
How can I find a nice way of basically saying our friendship was really based around her relationship with Tom (as I say I also don't like the way she treated him and continues to via the DC).
AIBU to be happy for and encourage this relationship with Sarah even if I was previously friendly with Chloe? I have known Tom for a lot longer and frankly value his friendship much more. I was happy to maintain what I had with Chloe but I'm not being told who I can and can't be with / have to be loyal to.
YANBU - you were friends with Tom first so it's none of Chloe's business.
YABU - you should be loyal to Chloe and stick by her.
