DH and I have been married 20 years, have 4 DC - 3 at school, eldest at Uni. He has a DS from a previous relationship who has always visited regularly but is much older - 27 now. He has recently split up from his girlfriend in a horrible way (he doesn’t want to move in with her after they spent years saving up for a deposit living with her parents). He resigned from his job without having another to go to and has been out of work since March. His mother has gotten sick of it and asked him to leave, he’s staying with a friend. Found out yesterday through my eldest DD that DH has been bankrolling him for a few months, paying him £1k a month!! DH also paying for therapy for him as he has a lot of guilt at not being with him as he grew up. He has now spent some of the money on a car he doesn’t need. DH has also found him a job with a friend of his. The money has been wasted it’s not gone towards renting a place or a deposit. My DD spent the summer working in a supermarket while he wasn’t working. I just cancelled a UK trip as we couldn’t afford it, DH has been asking me to pay for kids’ activities as he has had a dip in income due to the pandemic. I work p/t and I am furious that DH didn’t ask me before he spent this money on his son. He hasn’t been paying it from the joint account or I would have seen. We both have separate accounts other than the joint one. AIBU?
