Is OTHER wrong in the post ? POST : My mom and dad were married for 20 years before my mom decided she wanted a divorce. I could tell for most of my life that my parents didn't get along, but in my 20's they seemed to be fighting more frequently. I believe my mom was emotionally cheating on my dad and asked for a divorce. 

Their divorce was not pretty, my dad was a bit of a basketcase over it and became very depressed. The only thing that seemed to bring my dad's spirits up over the years was the birth of my children. He wanted to spend almost every weekend with me, which was sometimes annoying but looking back I'm grateful and miss our adventures. (Over the years my mom received a nice amount of alimony every month and was entitled to a portion of his pension when he retires.)

Several years later, my dad died due to heart complications in his sleep. He had a heart attack a few months after they split and his heart was weak. After his death, we had been contacted by his retirement system regarding his death benefits. Since my dad never retired, my mom will receive some of his inheritance. Well, most of it. I am my father's only living child and initially my mom told me if she were to get anything she would give it to me. Then she said she wouldn't be recieving his pension and is getting part of the inheritance but would like to use the money to help me buy a house or buy a new car, new furniture for my children/house, etc..."something my father would want."

Her and her boyfriend (who I don't care for) are planning on buying two houses, farm land, farm animals, planning on becoming medical marijuana growers, fixing up these houses, among other things. After hearing this I asked her if she was still going to help me out and she got angry and said she doesn't have any left and needs it. I asked her how since the money hasn't been divvied out yet and she began to explain what she needed it for and would have nothing leftover. It made things uncomfortable between us, so I dropped it ...but I've been brewing over it. Not only did she not speak to my dad for several years, but is planning on setting up a nice life for her and her boyfriend with my dad's inheritance. 

AITA for thinking my mom doesn't deserve the majority of it or am I being unreasonable and spoiled? I don't think she shouldn't get anything and I understand legally it may be what's  right, but I don't feel like it is ethically. I'm not going to push her on it. But I know if my hubby and I were to split, I would want my children to receive most of it, not him. 

Tldr- my mom and dad had been divorced for several years prior to his passing. She will be inheriting the majority of his benefits, which she initially said she would like to use to help me and my family out. Now she plans on using it to buy two houses among other pipe dreams her and her boyfriend share and gets angry if I mention what she previously said. AITA for thinking this is wrong?
