I've been with my boyfriend for three years, and we've been through a lot together. He is a very emotionally strong person - it takes a lot for him to break down. Over the time I've been with him, I have noticed something odd... he lives with his Dad and two sisters (one sister is moved out). They are all treated differently than him, they get everything they want when they want it, they can get away with anything, they are constantly loved on and praised, and my boyfriend (the only son) is ignored, belittled and shoved to the side. It has been this day since the first day I met him. Everything he does is never good enough, he is always being told everything he does is shit and that he looks like shit (he always looks great and presentable!). His Dad always bought the girls everything they ever wanted, from expensive shoes to cars. My boyfriend is cast aside, told not to even breathe near his Dads vehicles (his Dad refuses to teach him to drive, but teaches his sisters and then buys them cars), his Dad is constantly making my boyfriend clean EVERYTHING, the sisters never have to help. If they have a party with a bunch of friends and my boyfriend is out with me all day, he still had to clean it when he got home. They all go out to eat without him and constantly gang up on him telling him that "Dad doesn't even have you in his will!" Or "You're the least favorite kid".  My boyfriend tries to hide his hurt but every few months he has enough and breaks down to me. His Dad tried to strangle him in the laundry room because my boyfriend didn't fold the towels exactly how his Dad wanted them. His Dad is demanding a shit ton of money for rent from him even though his sisters are all older and don't pay rent. His Dad doesn't even know when his birthday is. He doesn't care.
