Hi Twice Divorced,

Welcome to the community. I"m sorry that you are going through a difficult time with your gf. I can imagine how frustrating it woul dbe to want to take things to a higher level only to have things put on hold longer than you would like.
What makes you believe she has BPD?
One thing some people with BPD have is what is called a
fear of engulfment. pwBPD feel things very strongly and sometimes they worry that they will be completely overtaken with their emotions for another person. They worry about losing themselves. Does that make sense?
