Need advice on whether this seems like strange behaviour to anyone else as I've been unabl to sleep much last night over it: My partner does a LOT for his younger brother but its never reciprocated when it comes to us. For instance - when it comes to my partners birthday, or christmas, we always get his brother lovely presents but don't get the same back in return, sometimes nothing at all. My partner is seemingly not bothered by the unfairness of this even though I have mentioned the imbalance in the past. Think of something like my partner would spend about 500 pounds on his present but then his brother would spend about 5 pounds on him and think that was acceptable and nobody mentions it, not my partner, not his brother, not his wife, I am the only one who voices that this is an impartial balance.
His brother has fairly recently got married which is another factor to this AIBU, as I can't help but feel that my partner paid more towards the wedding than was necessary - that doesn't even seem like a normal thing to do to me, not the contributing to the wedding part, but I personally felt like my partner contributed more to the wedding than was needed and he shouldn't have done so much. But that is over with and can't be changed now. We already got him and his wife a wedding present which was essentially a honeymoon but because they haven't used been able to go yet because of lockdown, my DP is talking of buying them a car because they have been talking of such for a while now (they do already have one so i dont think its even necessary personally)
He started a huge argument over it last night because I said that I don't think he should do it and he basically said I don't have any say in the matter and he can buy his own brother what he wants with his own money, but I feel like he may regret this and I'm feeling somewhat angry by his decision. But we don't share finances so it is "his" money but does that mean I automatically have no authority in the matter? Does anyone else think this sounds like his brother is taking the piss out of us financially? Keeping in mind that his brother is quite selfish and when it comes to my birthday he never really gets me anything and for christmas we only get a joint (and quite frankly, often crap) christmas present from him between us so I don't think, if my partner goes ahead with this, that it would be even appreciated or enough gratitude shown to us if we did this. And also, we already gave him money for the honeymoon and he has spent some of it already as he moved house so we have already given him a present financially and a car would then be an extra present on top of that. His brother is also the scrounging type and every time we see him he always says to my DP "Hi DP mate, could you borrow me X amount of money" and my DP never says no, but he never asks him for money back so this is always him borrowing money from us, not a two way street. His wife is also quite a grabby type too.
YABU and he should be allowed to buy his brother without my input
or YANBU and I should have some involvement on whether he should be able to do this or not?
