Family as follows: mum and 3 sons. All sons are mid to late 30s currently. The mum is retired and doesn't need care / help. No-one in this situation has a disability.
Son 1(oldest but only by 18 months) moved out at 18 for uni and now has children and a wife. Pays his own way and no help from his mum (financially or with childcare). Not well off by any means and has had periods of financial struggle through redundancies, high childcare costs etc. He and his family live fairly frugally eg rarely eat out, get takeaways or go on holiday.
Sons 2 and 3: still live at home with mum, do not contribute in terms of rent and very little in terms of doing things around the house (their mum still does their washing, pays for the food shopping, cleans for them and does the cooking). She pays a gardener and handyman to do the things she can't. One of the sons lives in the annex of his mums house so has his own entrance and living area etc. Both sons have worked here and there but not consistently and have made it clear it’s not a priority for them (currently one working and one is not). They both mostly play video games. Mum takes them out for meals regularly and buys them a takeaway at least once a week. She also pays for their holidays, phone bills, car insurance etc. This arrangement has been going on for 13 years so not a short term arrangement.
I can understand this situation happening for a few years while everyone figures things out and gets on their feet. But 13 years in it seems that there is no plan from the sons to change this situation, they are happy with the arrangement and are not saving for house deposits. The Mum has been saying for many years that she wants to sell the house and downsize.
I don’t know if I am taking fairness between siblings too far, but if I was paying for everything for sons 2 and 3 for such a long period I’d be putting money aside for son 1 or his children to even things out a bit. Or preferably pull back on what I was paying for for sons 2 and 3. If I was cooking cleaning and doing everything for sons 2 and 3 I would try and help son 1 out with childcare a bit. AIBU to think this? If you have grown up children living at home permanently and children who live independently, how do you manage fairness, or does it get past a point where that matters?
