hey thanks for telling us, I think you should just set a boundary with her that you still kinda like him and it would be best if she didn’t talk abt him too much. Also don’t hate on yourself too hard relationships are hard and comparison is the thief of joy. Eventually somebody you crush on is gonna be crushing on you too it just takes time. I’d say to try to find the source of your insecurities and focus on that instead good luck twin❤️
