AIBU to spend this money how I like?

[HarrySwotter]

I've just received a small amount of money from my Gran. She'd sold something and had given all her grandkids some money from it (£400) to treat ourselves and her great grand kids (me and one cousin have DC).

DS really could do with a room spruce up. Fresh paint and the like, a bit of furniture and accessories so I've decided this is what I want to do with it as a surprise for him (he's only 3) and his room at the moment hasn't really had much effort put into it yet if that makes sense.

My husband is pulling his face at my choice of how to spend this money. Namely because of my step kids and how unfair it apparently is.

DSC stay 3 nights a week and have a room which they share which was done about about the time DS was born. There's nothing wrong with it.

AIBU to say this is what I'm doing with this money and I'm not going to be guilted about it? My gran will love the fact that I've treated DS (she adores him) with it and I want her see we've done something nice for him with it that will last a while.

He wants you to spend your grandma's money on his kids room that's in a constant state because neither they nor he can be bothered to clean it? No thanks, I wouldn't be spending a penny on it.

If he wants to waste money on carpet/decorating that will be wrecked in 6 months he can do it out of his own wages, let him work overtime if he's so desperate to bridge the gap of so called fairness.

Campervangirl hit the nail on the head (and a congratulatory high five to you for getting out of it) these types of blended families are a huge PITA that breed resentment and it almost always stems from the dad being a Disney dad too.

I'm annoyed even reading your post.

Tell him to go bollocks.

@BulletTrain not if he wS living with a partner who had kids and then he had kids it wouldn't which is what the reverse meant and i agree people would have different answers then
Personally I think OP should spend what she likes but then can't complain if the Dh then spends family money doing the kids room or his money to make theirs nicer
Personally i couldn't live in a house with a really messy room and would insist its done
Maybe op could just suggest to her dh get the room back to a decent condition and help just him just this once , wash carpet or get a cheap rug, fix a blind as a broken blind means they probably have people looking in and promise dsc if they look after it going forward , they will gradually do it up a little providing its looked after and thats her gift to the dsc her time helping and maybe a new blind
