This short song pretty accurately describes it.
I have a brother close to my age that I grew up with until he left for college. Our life was exactly like that song except for the book reading and never fighting part. And this story is much like the MLP FiM Royal Wedding special.
He's successfully graduated college and got his first job in his field at the cost of moving all the way to Florida. He's had a girlfriend going on several years now whom he met at a time of weakness during his spiritual development. She's very forceful of her views, an activist really. So naturally he listens to her push her views on people and him every day. He was finally about to get away from her by moving out of state but she played the victim card and sent a suicidal message to her sister. After the hospital he was trapped to cancelling the break in the relationship to keep her from killing herself.
He never planned on bringing her there but my brother is so considerate he would sacrifice his potential happiness for her. Before this he was leaving it up to fate if the relationship would hold out or they both move on but now he's engaged to her and I can't help but feel like he's trying to make himself love her enough to marry her and she won't kill herself. How can you go from 'Maybe we'll break up, maybe we won't.' to promises of marriage?
I know my brother, he's the type of person to wait and open a door for a stranger walking 10 feet behind him and offer them a shopping cart at the store. He loves people and doesn't like to see people unhappy. And now he's about to attach himself to this girl for life. I can't believe this villain is using my sweet brother to control him for her own benefit.
