Hippy,
Hey, being with someone like us is probably extremely frustrating. Like Sway mentioned with her friend, a way I've found that relationships 'stick' together is when the other person is unconditionally supportive. "I support you, I got your back."

I think, if you feel in yourself that that is something you can do (even if it's just a plutonic relationship), it is a great way to show support. That said, you also have to keep yourself healthy and safe (not be codependent).

Honestly, I can't imagine what it is like to be with someone with BPD, although since I've accepted my diagnosis and I'm getting help and support (being proactive) my partner has been way more receptive. She is constantly supportive, I am so grateful for that. But our relationship is not void of struggle or frustration, it's not always easy. Just know that. Find support from other people whose partners have the disorder. You've already done the first thing, you're asking for help!

Yay Sway for books!
