I originally had a minor conflict with my girlfriend, but her best friend came up with a bunch of crazy ways for her to deal with me and tortured me, making me want to break up. her best friend

Two possibilities: 1. Your girlfriend’s best friend is just out of friendship and wants to test whether your love for your girlfriend is true; 2. Your girlfriend’s best friend is attracted to you and wants to take advantage of it I want to disturb you and your daughter so that she can take advantage of it. There is a saying that goes well: "There are only two possibilities for a girl to break up with you: one is that her best friend doesn't like you; the other is that her best friend likes you."
