Hi, I have an serious question

I am a single son 19 yr old . As far as I can remember from I see my father getting home drunken and causing problems. At one night he came , brutally harassed my mom , So she took me to her mom's home. But after few years , though I was in my grandparents home slowly problems got solved . Dad decided to go to gulf to earn. But whenever he gets a chance he gets drunk and cause problems.I tried my best to stop them but later times heals. Happy for years. And after my stay till 7th grade. Mom and dad together bought a house by taking house loan and moved in. And the tragedy of my life started in 11th . Dad lost job. And now he is home ,he brought his parents home , I thought it was gonna be a happy family .He tries to get new jobs but it's didn't matter if we had a happy family. Then soon poverty started . Mom now had to pay both house loan and expenses. Dad , don't know why he started feeling bad for not having a job , he releived it by getting drunken and causing problems . Soon it got unbearable. Mom's suffering . I was in boarding school during my 11 th and 12 th . But due to dad I can't even sleep properly cause if my dad or mom did not attend my weekly allowed phone call , then father most probably got drunk or he started fighting due to some small problems .Now 19 back to home tried my best to get them together coz I need both of them . But somehow dad starts a problem . Slowly he even doesn't consider me as his son and even consider divorcing I fear for my future and my mom I fear of not having my own home I am asking if its turn to divorce will I be able to live in my house which he owns half but now my mom's pays the rest of the loan. Will I have any asset for my future venture , will I be able to say go to college Will I be able to got to foreign country for future studies Plz help
