I'm on an OLD site, not really active but there nonetheless. Last week my friend's ex husband sent me a message. I responded out of courtesy, asked how they were and they sent subsequent messages and then suggested they were looking for a FWB and had considered asking me, I didn't respond and they sent a further message to say they should probably apologise for their last message. I responded by saying let's just leave it there and they have replied with understood. Should I tell her? I feel like I should but don't know if that is stirring trouble, they're still very much entwined. Most bizarre why he would do this.
