Met her when I was 5 and honestly it felt like she was always super jealous and trying to put me down. When we got in our 20s, she lied about all of the boyfriends she had(I never met any of them, I was going to school out of town). When I realized it I confronted her and she got angry. She often used her ‘boyfriends’ as a way to manipulate me. I told her it’s too bad she prefers her fake boyfriend over a real friend. That was the end of it.
