You can do it! You can ditch them and find someone who likes you back, her ❤️ Things will work out and you will date her.
Also, I saw from a previous post that they befriended their ex that hates you and turned into a jerk, which I don’t think is their fault (it’s probably the ex’s, mean people can be manipulative) but it’s definitely unhealthy to be friends with a manipulative, mean person, even if they don’t know the ex is mean (which they likely don’t).
