Not that long ago, I got into a fight with a best friend due to lack of trust and a bunch of other things. Our friendship often left me feeling neglected, set aside, insecure and envious because she's the type of person who goes from friend to friend as if they were clothes from her wardrobe. We haven't spoken to each other since then, and she comes to me asking for a second chance. I don't think I will be able to continue this toxic friendship and I certainly don't want to go back to feeling upset anymore, but at the same time, I want to give in and start over with her. Any input?
