DM and DF have a terrible marriage. DF is emotionally abusive and pressurises DM into sex to the point - I suspect - of rape. DF blames DM for all his unhappiness and can barely bring himself to say a pleasant word to her.
Of course, on the surface all is well. DM has only confided in one friend who is in a similar situation and myself, but otherwise the world thinks they're a happy and privileged couple with plenty of money, lots of lovely holidays, children and grandchildren.
DM has had a lot of counselling both on her own and with DF (although the latter has been spectacularly unsuccessful) and seems to be coping ok. She has a rant to me periodically about DF's latest fuckwittery and we try to laugh about it, and I reassure her endlessly that she is a kind, thoughtful, strong person and not the cause of DF's unpleasantness in any way.
But I'm finding it really hard to hear of DM being in such an unhappy situation. DM and DF have been together since school and it kills me that she's never known anything different. She knows DF won't change but says it's too late to leave him, doesn't want the lifestyle change etc.
I can't tell DM I don't want to hear it any more. I know I'm a bit of a lifeline to normality and I can counter the gaslighting that goes on. But obviously I can't force her to leave him. And she doesn't want me to say anything to DF because then he'd be even worse to her. He does NOT cope well with being challenged on anything. Ever.
What should I/could I do? Do I just have to butt out and carry on being a safe shoulder to cry on? Is this enabling? I'm in such a dilemma as I'm scared of making things worse but hate seeing my mum living a life like this.
