Should I wait or not?

I have been in a sort of on and off relationship with someone, she called quits on it in November and said she wants us to be friends, which I declined.
We stopped talking but she continuously kept coming back. She shares extremely personal things with me which to be honest one doesn't share with everyone normally.
We met a couple of weeks ago and she said you've changed and all the changes are "GOOD CHANGES"
She's visited a psych recently who diagnosed her with severe depression and borderline personality disorder. Only two people know about this me and a friend of hers. No one in her family knows about this.
I really like her, but I need to know what should I do? I've told her that I am not looking for something casual and I want what I want which is to be with her.
Should I wait for her or not?
