My father used to gamble and cheat on my mom. He lost all his money and thugs used to come to my mom's office asking for money. It's been 7 years now. I thought it was all okay but recently he started stock trading online and has invested a lot of money in it. I think he will go back to his old ways. He is inconsiderate to my mom and me. My mom has always helped him financially and helped him buy a new house too.
Now, he says that he wants to sell his house. He also is very rude to my mom and me. He also bad talks about me and my mom to his friends and family telling that we don't take care of him etc. What should I do now? Should I confront him or not?
