Fed up with the way my mom treats my dad

[Eric4Nitrous]

I posted a couple months ago about my mom going crazy because my dad bought a dually. Well, he saw a Motor on the internet that he wanted to buy. 540ci 920hp N/A. He has more than enough money saved up to buy this motor for his chevelle, and my mom calls me up today cussing me out and calling me every name in the book..and blaming me for his obsession. She said sometimes she wished i was never born I went over there to talk to her and she locked me out of the house and told me to get the **** out of her house. I was like WTF?? So dad comes over to my house just a little bit ago and says he's not gonna get anything else for his car because of the way she reacts. She told him that even if he has the money for it, he's still not getting it. But yet she can buy a damn supercharger for her car, and everything else and he can't even buy something that he's been saving for??
