I’m 18 and I have a younger sister who’s 16. I like this dude. I have a lot of confidence and self esteem issues, so it takes me a lot of courage to talk to him. My sister always tells me she never has time for boys and how she’s not interested in dating. However, as soon as she found out I liked this guy, she started flirting with him. She also says things to me like “I know you like him, but lowkey he flirts with me” or “maybe if you sat next to me in class he’d actually look at you” What the f***? I understand that sibling rivalry is a thing and I know siblings are competitive, but none, and I mean NONE of my other siblings or any other siblings I’ve seen has done something so cold. She doesn’t even want to date him. She just wants to remind me that he doesn’t like me because she wants me to feel inferior. She does this kind of thing with friends to, always reminding me that people only hang around me because of her. But this is bothering me so much more because I really like this guy. I was hoping I’d gain the confidence to ask him out, because I’ve never been confident enough to ask anyone out before. And look, if he really does like my sister, I can’t do anything about that and I’ll have to move on. It just bothers me greatly that she feels the need to decimate what little self esteem I have. Again, none of my other siblings have ever done something like this. Is this simply sibling rivalry anymore? Or do I have a toxic relationship with my sister? Can siblings be bullies?
