NadiaWadia Yes, that's what she's writing, I agree.
But I still have a fair point. She could be putting pressure on him without realizing it.
I wasn't trying to compare DH and her DS, I was trying to point out that not everything is as it seems from one perspective.
FIL will do "favors" for people and then hold it over their heads. So he'd come across as a poor victim whose son was just a terrible person or refused to help him after all he did for him. When really it was more of a "give a mouse a cookie" situation. We knew if he asked for us to wipe the counters it would escalate to dishes, to sorting laundry, to cleaning the whole house in incremental steps that seemed reasonable. If we stopped at simply wiping the counters he would tell people he does all this stuff for DH but he won't even put away a few dishes. It's not to compare, it's just to show, from being on the receiving end of bullshit from both sides of the family in regards to dysfunctional families, there's a whole other side to these things.
She says she "needs" to do his laundry or he'll take it to the dry cleaners. She says she "needs" to get his toiletries or he'll buy more expensive ones or use his brothers. There's an awful lot of "needing" to do things for him, that really don't need to be done.
In my experience there's rarely an innocent victim in any relationship, especially a parent-child. Both are usually contributing their fair share of grief to each other. Which is why I suggested it would be a good thing to kick him out.
I'm not saying that DS is in the right by any stretch of the imagination. But, I also don't believe OP is blameless in this, not saying she's to be blamed either. I would bet it's an equal contribution from both, where they're both wrong on some levels and right on others.
