Hello Nicole.
I am very sorry you are going through all of this at one time. I am sure you are overwhelmed, but you have nothing to feel guilty about for making an adult decision to keep yourself and your mental health safe. No one deserves to be mistreated in any manner not even in a relationship, friendship or otherwise, so id you are safe then you made the best decision for yourself to no longer be friends with this person. I hope things get better for you soon, and you feel better soon. Take care. Soidhonia
