<human>: A few years ago, my uncle died and left me a huge portion of his estate, an amount valued in the upper six-figures. My brother was not included in this, and I felt this was unfair and immediately offered to split the money with him. At that point, I was unaware that the money was in an inherited IRA and as such is subject to taxation (I have to pay taxes), there was no way to split the account without me giving him money as a gift, and a woman who had married my uncle less than one month prior had obtained legal counsel and was contesting the entire estate. 

The entire situation was extremely stressful to me, and I ended up hiring my own lawyer and had to pay around $10,000 to defend against this woman. I asked my brother to help with legal costs, as we were going to split the money and he said that he just couldn't afford it. This is despite the fact that he makes much more than me and took a tropical vacation and a golf vacation during this time. 

During this ordeal, my brother was constantly calling me to tell me how I could gift him money, but was completely uninterested in the stress I was going through moving the account and dealing with my uncle's account managers who tried to block me from moving the account and were swindling my uncle. 

Once the account was in my name, my brother began demanding money and I told him that I wasn't comfortable giving him a large amount as a gift. He became irate and hung up on me. We didn't talk for over a year, and the only contact I've had is emails from him telling me what a rotten sister I am. 

My mother has sided with him, telling me things like "I'm just going to put this out there, you said you'd share". When I try to explain how uncomfortable I am giving him money, she refuses to understand the tax situation, my brother's lack of help and lack of loyalty. 

Despite the fact that I think what I did was right, I still feel guilty. Should I? Reddit, what would you have done?

Can you give me the gist of the text in a nutshell?
<bot>: Was going to share inherited money with brother, he acted like an entitled asshole. Mother is siding with him. I feel bad still. Should I?
