News from battlefield

I was after few phone callings with her. I feel angry and weak. We are after one week of break with any kind of contact from me - only she was texting and I answered but that's all. I decided to set this kind of boundary due to her behavior. It was enough for me.
Yesterday she decided to call me. During the phone call I explained her why I was angry at her. First - she tried to deny everything. I quoted her words. She says "I was only joking!". Then she blamed me: "You behaved just like my ex-boyfriend! He also did not speak to me for weeks! Well you know what they were boyfriend for me was!". There also was full list of my sins, slander my mother about things she did not do. And also "I don't trust you and I don't believe you!". I gently ended this calling, it looks like never-ending cycle. Also, I stated that the reason of our problems could be her emotional instability.
Then she wanted to speak second time. She was calm and pleasant. Instead of blaming she tried to apologize and explain. It was long and exhausting calling.
Today we talked third time. The current state is to take a break "like a dudes" and wait until end of February to make definite decision about us.
I think she provoked me to take offense, then blamed me and compare to ex-boyfriend. In opinion of my friends my reaction was appropriate. I tried to present situation as objectively as I can. Also, during callings I established that she cannot trust anyone and told it to her. She replied that I am right, but "maybe if someone make things that I want I can trust then". I don't believe and don't trust her.
I am afraid that she is immature or even toxic girl. I'd like to make my emotional life better. My plan is to set boundaries and prepare to definite break-up. I am looking for advice from my friends.
Now I am thinking that second chance is not possible - there is a lot bad behaviors and it looks like I just can't stand anymore.
Do you have similar experience?
Thank you, BPD Family

You give me a hope in these black days
