My friend has started to going out with a very nice man. She seems very happy and I've kept my mouth shut over this so far.
He was dumped quite abruptly by his ex a few weeks before they got together and took it very badly.
The thing his, he has got back in contact with his ex. He's gone for a drink with her and has gone round to her flat a few times. There are no children involved. The reason apparently is that the woman has mental health problems and he's worried about her.
My friend is fine about this but I think she's mad. I wouldn't be fine with this. No matter what happens I'll support her, but should I be ready with the tissues? Should I say something (gently)?
