Good (male) friend of mine got married last summer. Delightfully in love with his new wife. 6 months on, she's walked out on him 
She emailed me to tell me and ask me to get in touch with him as he needed support. (have left message for him, and checked with mutual friend who has spoken to him - he's OK though pretty shaken up)
But now, another email from her asking for my mobile number "because of how things are"
She's sent a similar email to at least two other mutual friends.
I've been friendly with her the last couple of years, since she's known my friend, but we're not close.
Does she want to keep in touch with us all after the split?
Or is she collecting all his friends phone numbers so she can harrass him?
What woud you make of it?
