Ok, I'm going to try and keep this as short as possible.
My DB is 32 and lives a couple of towns over from my DM with his DP. He is close to my DM in terms of keeping in regular contact and helping her with things around the house, but I think he takes serious advantage of her and I don't know what to do!
So, a brief list of things he does:
- Takes all his shirts to hers once a week for her to wash and iron because 'it takes him ages to iron his shirts'
- Also brought his and his DP's laundry over for her to wash and iron so he could come over earlier on Christmas Eve.
- Gets her to make him lunch for work every day which he then pops over to pick up every evening. His reasoning is she likes doing it, hers is she'd never see him if he didn't come and get his lunch
- When he came over for Christmas, he stayed in her bedroom and she was turfed out to the spare room. When I challenged this (it really pissed me off) I was told 'well, she offered it. Why wouldn't I take the bigger bed?'
- When he stayed over Christmas he got her to make him breakfast every morning and watched her clear it all away for him as well.
So as not to drip feed, we lost my Dad last year and my mum is now 'on her own' for the first time in her life. I moved home when all this happened to help her out, but will be moving out again soon. She originally planned to move back to where she grew up (about 2 hours away), but now thinks she should buy a smaller (but much more expensive) house in the nearby area so that she can be nearer to him. She seems to think he's too delicate to look after himself so never tries to make him stand on his own two feet and he really takes advantage of this 
What would you do?! AIBU to have serious words with them both about this? I don't want to upset either of them, especially when my DM is so vulnerable, but this is driving me crazy!
