Basically it's all down to him flirting around another female friend X. The DW has had enough. She says he stares at X, has said 'he'd have her' when X was saying she felt old. Said this in front of DW.
It doesn't sound bad but I know I wouldn't like it. There's more to it too. I don't think he's cheated but he is giving X too much attention. He is a major flirt, very complimentary but doesn't compliment DW. Says he's with her isn't he so why should he?
He's such a good bloke in other ways but if he's making his DW feel like this then it's bad.
I hope they can salvage this? I suggested Relate to DW but she said there's no point.
Just wanted to offload really as am keeping this to myself. She told me in confidence. None are on MN.
