Is your mom knows that what your dad is doing to you? tell her not to give money to father hand, tell her to give that money to you or tell her to put it in your account then. What type of father and man is he, if he can't take care of his own expenses instead of spending his own son and your moms hard earned money for himself? is he's spending child support money for his uses? what a shame? he looks like he's selfish father I think. You are 17 years, why don't you get a small job in somewhere to support for your self? then only your dad will feel shame himself about what is he doing to you? other people will also get to know about your father behaviour too, they should blame him too. I'm very sorry about you. God will help you other ways to you and take care and study good.
