I am very confused. Glad I am in therapy!

I have been in a relationship with a BPD for over a year. During that year she has broken up with me 4xs, the most recent this past Weds.
In the past I would panic. I would call and she would get very angry. I would wait to see if I could speak with my rational ex (ha ha) and she would threaten a restraining order.
Once I let it rest and paid no attention she would come back begging. Longest break: 12 days.
This time she was calm. She came over, cried, held me and said she loved me but we were too different. She told me my friendship was "irreplaceable" via text before coming over to make the break... .
I knew it was coming from that text.
She proceeds to tell me she wants to be friends, that we were meant to be friends.
I am not buying this because of the past yet she seems so cool and calm. She keeps repeating she hopes I find "peace". I think she is chanting this to reaffirm to herself.
My birthday is Saturday and she wants to take me. She keeps saying without my prodding, "Under no circumstances are we getting back together. If that is your plan, to re-hash our relationship, make other ones".
I am very confused. My birthday is Saturday (next). I am thinking of not contacting her until she does me. What do you think posters? Is this really over? I don't want to be her fall back bestie, that's for sure.
Thoughts?
