Will try and keep it short.
When I first met DH, he was living in the home he and his ex had bought together. When they separated (a year after buying the house), she wanted to move back to the town her parents lived in so he bought her out and the house was transferred into his sole name.
I met him around 1 year later and we've now been together for 7 years married for 5. When we moved in together we agreed that I'd pay for some renovations the house needed and he'd put my name on the deeds which we did. We've now lived in the house together since and I consider it my house. We have together over paid on the mortgage and renovated it since using both of our finances etc..
We are now selling the house and it's obviously worth quite a bit more than it was when he and ex bought it.
Ex has now suggested that he give her a lump sum from the sale "for their children" considering its "their" (his and hers) house.
DH seemed to initially be okay with this idea and didn't seem to think he needed to run that by me.
I've said no he shouldn't be giving out lump sums of the proceeds to his ex who was already paid for her share of the house years ago and certainly not without discussing it with me. And he certainly shouldn't be of the idea that it is in any way her house considering I've been paying the mortgage and for work doing to this house for many more years than she ever did. It's OUR house and the proceeds are OUR money.
Aibu to not want him giving her any money? If he genuinely came to me and said he wanted to put some in savings for DSC I'd probably agree but I don't think it should go to her, there is no need. And I certainly don't think it should be done under some misguided idea that it's still her house and therefore she's due anything.
We also have our own DC now too and are buying another property which may need future works so I don't want to be dishing out lump sums to this person and that.
