Hi GfissuesBPD03,
Welcome
I'm sorry that you are having difficulties in your relationship. Rejection is often something that pwBPD struggle with and the thought of you having a relationship with someone else may have triggered that feeling of rejection.
However when I told I saw someone when I hadn't she got angry at me. What can I do to communicate with her about this and make this work. She is queer and I don't mind her seeing other women sounds bad but it is just my boundary unfortunately.
What made you want to tell her you saw someone else when you didn't?
Do you really want an open relationship or are you just saying that because you don't want to rock the boat? If you are ok with the open relationship, what part do you need help talking about with her? (not trying to sound harsh. Seeking clarification.)
