Friend of mine has just broken up with her DH, after having an emotional affair all summer with another of our friends.
Friend and OM extremely catholic; friend's DP is atheist. It has caused friction in the past.
The OM is in the process of moving away (which he knew about before the affair started). OM is miserable to the point of suicide about moving away. Friend is miserably at her parents'. Friend's (D)H is miserably at his parents'.
OM and friend are asking me what to do, saying they don't know what to say or do etc.
I haven't a clue and particularly haven't a clue how their faith and the rules of their religion fit in with all this, i.e. if there is anything I should be advising in particular.
My only real viewpoint is that friend and OM are distinctly better suited to each other than friend and her DH.... catholicism, interests, outlook, personality etc.
I'm saying stay calm, don't make any hasty decisions, and trying to make sure they each have somewhere to stay and that they each keep talking. 
Any advice, anyone?
