HI DatingBPD,
I'm sorry that your partner is not wanting to disclose your relationship to each other. I really like
Lady Itone's suggestion of starting by telling only a few close friends and family members. Now that you are living together I think that's a sign that things are heading into a more serious relationship.
It's important that you are able to keep your voice in this relationship and that often means asking/saying things that your pwBPD may not like to hear. We have a communication skill called
DEARMAN that can be used to talk to your pwBPD about things you want and need.
If you would like to practice how to start the conversation, we can help you tweak it and work through wording. If you are comfortable having the conversation, can you share how it might go here?
