I broke up with my girlfriend a few months ago. There were a lot of arguments and fights and I wasn't able to make her feel loved or cared. I thought I'm only making it worse for her and decided to break up. She did not take the breakup properly and not able to accept it's over and is very hurt.

Though I don't talk to her I text her as I want to be there as she goes through this difficult time. She reached out to me a few days ago saying she has been diagnosed with BPD. 

How can I help her get through this? All our conversations are about how I don't understand her. I'm trying to tell her she can talk to me about anything, but she feels I'm pushing her away as I asked her to get help from a therapist.

I really want her to feel better. Please suggest how can I help her through this.
