My sister has been dating this guy for a year, and she seems happy. But ever since they started dating, she doesn't speak her mind. She doesn't have an opinion or a say in what she wants to do. I've been noticing that he is kind of controlling. Like it doesn't matter what my sister wants to do, they always end up doing what he wants. Even a friend of mine noticed that he is controlling her too. He is a great christian guy, don't get me wrong, but he controls her like a puppet. Just last week me and my sister planned a movie night, but she canceled on me because he didn't want her to watch a movie without him there. It's just annoying how the little things make him mad and he tells her no, and she listens. I've tried telling her that she needs to stick up for herself and voice her opinion, but she just shrugs it off like she doesn't see a problem. Is she just so in love that she can't see the controlling side her boyfriend has?? How do I help her understand that??
