I don't give up easily and love her, I've told her the isolation treatment is not for me but yet it continues. I want it to work out, it's becoming very mentally challenging for me. Please help!
Hi Niulatu and welcome! I'm so sorry you're going through this.
The bolded statement makes sense but in terms of BPD, it's also a huge challenge. The isolation is her own insecurities creating space to process her emotions and fear of abandonment. Asking her to stop could come off as invalidating, and it all really comes down to communication that makes her feel safe and understood.
How long have you been separated? Are you communicating at all? Give us some details so we can try to help.
