How to help friend's STBX

[Hereward1332]

My friend's marriage was in difficulties, and he started an affair. His DW has left him. Really wondering how best to support her - I'm sure she has lots of RL friends, and support on here. Should I offer my support too, or will that be too close to home - STBX and I have been friends for 20 years, long before they met. Is it better to stay out of it unless asked?

If it were me, I'd stay out! Divided loyalties is not a stable situation IMO.
If you are emotionally attached to her yourself, then I understand why you would want to support her. But be prepared for massive fallout in that case! Your friend might not forgive you.
If you keep out, I think it might be nice to let the DW know you are not siding with anyone, so she knows that you don't disapprove of her actions.

If she asks for help, you still have to think about the fallout IMO, You might not be in the best position.

I have assumed you are a man!

If she is on here I would leave her threads well alone and let her vent or whatever without having to worry that you are reading everything.

If you know her user name let her know so that she can change and remain anonymous.
