Welcome to the family, loosinmylight!

I’m so sorry for what you’re going through. It’s actually pretty familiar to hear around here. We’ve been there — or still are there. Because if that, we have a lot of experience to share and a lot of support to give.
Perhaps when you feel like it, you can share a few details? That can help us know his best to help you.
For instance:
How long have you and your loved one been together?
What sorts of BPD behaviors are causing problems?
Could you share a description of a recent incident — sort of a play-by-play?
Again, welcome! We’re here to help!
