My friend has just found out that his wife has been having an affair. He is devastated, not sleeping and struggling to eat. He wants her to move out as he feels he can't cope with the pretence of normality, though he is not putting any obstacles round access to DCs. I have offered my spare room for as long as needed. The problem is that she doesn't want to move, and I wouldn't be surprised if she got a bit nasty. I have advised legal advice, and googled some options which I will give him later. After research on here I also advised gathering evidence of the affair, and a sexual health check 
. Is there anything else I should say? I have spoken briefly to the wife and made the offer of a place to stay but we're not close - I am trying to be quite neutral to her so she may accept the offer. I don't feel at all prepared for my current role of agony cunt, especially with this friend as we're both introverts and have never even touched on emotions in conversation before. Any advice from the more socially proficient out there? Thank you!
