Too Gullible?

Jade
So I have a (sorta) friend, let's call her Sasha, that was kind of toxic, so I confronted her. It was fine at first and then she got really aggressive and blocked me on all social media. My best friend, let's call her Lori, used to be Sasha's best friend and kind of hates her now. So on to the point, Sasha texted me basically saying that she's trying to be a better person, that she really wants to be friends again and talk. She also said that if we don't end up being fried a it's ok. I really don't know what do to. Am I being too Gulible?
