My parents in law have what I feel unreasonable expectations of my partner(48). His mother has asked him to promise to look after his brother (31) if anything happens to them. There is nothing wrong with his brother apart from being lazy and spoiled. He has a well paid job(£40k) works from home( still lives at home) Ha pays £25 per week to live there for everything including for his girlfriend. His mum still makes his lunch!! His sister (27) lives not far from them (2 minute walk) and her boyfriend and her earn £100k. Their parents still pay so much for them including helping with the deposit on their house, doing all the diy and buying/ installing a wood burner as they are” struggling “ . My partner has struggled all his life. We don’t earn much , I work for the NHS on just above minimum wage and my partner was relying on overtime to pay for any extras but that has dried up. Just had to spend nearly £3k on fixing our car so money is really tight. So are we unreasonable in saying no? Why can’t he go to his sister’s as she has a spare bedroom? We don’t even own our home and plan to downsize when our daughter moves out! I’m 55 and I really don’t want his lazy entitled brother living with us, expecting me to clear up after him in my retirement!!
