Hi Gusty and

It's nice to meet you. This is a great place to learn, detach and heal. I can highly recommend getting involved in others' threads, as everyone here is at various stages in the process and you will gain a lot of insight from doing so. There is a great deal of experience and wisdom on these boards.
First, can you tell us a little more of your story? When did the r/s end and how? How long were you together and do you believe your partner to have BPD or are they diagnosed? Share as much as you like and let us know what you're having difficulty with right now. We can help.
Love and light x
