Is OTHER wrong in the post ? POST : Okay I have to admit, I feel like I'm NTA but my wife has gotten in my head and I need a third party opinion.

My wife and I are trying to buy a house. We are already qualified and are ready to make an offer. Currently with what we have and how much we make, we will have no problem affording a house, however buying down the interest rate would make our payments feel much more comfortable, but its not a necessity. 

Several years ago, my father gave $10k to my older brother to purchase a home. Armed with my knowledge of this, I asked my father for a small loan of $2,600 to help buy down our interest rate last week. Unfortunately he said no, which is whatever to me but my wife on the other hand wasn't so happy about it.

Now my wife is claiming that its unfair treatment that he would help one of us siblings out but not the other. I reminded her that he had helped me out in other ways in the past, but regardless, it's a deal my dad made with my brother and as far as im concerned its absolutely none of my business. Just because my dad helped out my brother doesnt mean im entitled to any money whatsoever. 

I may be a little harsh but i keep telling my wife she's acting entitled and selfish to expect someone to loan us their hard earned money and now we're in a big fight over it because that type of mindset is, in my opinion, so juvenile and immature. She is claiming she's not acting entitled but she thinks its a great injustice that we aren't being gifted some money. I'm sorry but in my book, thats entitlement.

So, am I the asshole for not agreeing with my wife and telling her that she (we) have no right to feel entitled to anyone's money?

tl:dr- My wife feels it's unfair that my father helped my brother out financially several years ago, but wont give us a small loan to help to buy a house and I told her she's acting entitled to my fathers money. AITA for calling her out on it?
