I do think that H didn't appear v happy even when he came home to eat, he didn't interact with anyone much except son and you at times. I am afraid that unless he gets help from professionals for his severe depression / and drinking this is going to be a very long road. The best you can do is what you are doing and taking steps to make yourself more financially independant. The girls deserve the same as your son. This will only cause bigger sibling rifts.Sorry jmo. I do know men that treat sons diferently and their daughters as second class citizens but it is usually a culture thing,still makes me cross in this day and age.
