My friend recently started dating a workmate of my DH after bumping into them on a night out. She felt quite uncomfortable at the link so said that she didn't want to discuss their relationship with me, fair enough.
I knew DH's mate has a grown up son (early 20s). I didn't tell my friend as I felt it wasn't my place to say, plus I didn't feel it was that big a deal - the mate is early 40s, more unusual to not have any children I would have thought, the son is an adult, plus I knew that my friend isn't that bothered about having her own family so wouldn't be a problem if he didn't want to have more children. I thought it was up to him to tell her when he felt the time was right in their relationship.
Anyway when he did tell her she went mad at me for not telling her first. We didn't speak for a while then she asked to meet up - we discussed it and agreed to draw a line under it and move on. But a few weeks on she has just fb messaged me to say she can't do that as she feels I didn't act in her best interests, don't 'have her back', I'm not a loyal friend etc - she seems to be ending our friendship completely over this.
I'm really upset by this as we have been friends for over 20 years and I have always supported and been there for her.
Sorry this is so long - basically AIBU for not understanding why this is such a big issue or am I the one in the wrong here?
