what to say to friend whose husband left for second time

[Mummyjoon]

my friend's DH had an affair very shortly after birth of DS1. He moved in with other woman.
I listened and supported, expecting them to resolve things and get back together.

They did and had DD.

A year and half on he's had several affairs and she is organising a divorce. We were friends for many years and i liked her DH.

She made no effort to maintain friendship when they got back together, why? I don't know. Maybe embarrassed at what i'd been privy to.

She has now contacted me, first time in 1 and 1/2 years. Meeting up tomorrow.

So glad she felt she still has a supportive friend in me but unsure what to say- i stayed on the fence at times because she so desperately wanted to get back together.

want to support & help unsure how!

Just be there for her.
I know it's annoying, but just this once she really needs a rock to support her.
She trusts you. She tried to give her marriage a chance and it failed. Just make sure she doesn't let herself believe it was her fault.
You are a good friend.

Thank u dollius!
She probably wants someone who knows her really well to just listen without judgement.

It's hard to just listen without offering opinions & 'resolve' things but i think that would be best.
Thank u for the advice

Yes, definitely just listen. If you feel the urge to say something, try to "reflect back" what she has been saying to you in the previous few minutes - ie, summarise what she has said in your own words and ask if she agrees with you on that.
It will make her feel supported.
Good luck.
