I like talking with my friends. I enjoy socializing at fun outings. How do I manage to still do things I enjoy doing with my s/o who also enjoys these things without unintentionally forcing a split when she becomes fed up with me talking to people? Is this a jealousy response on her part? Was I not giving enough validation? Do I just let it ride and let her be angry the entire time next time and let her self soothe while we are with company?
I don't think there's a 100% solution. Try going by yourself sometimes and enjoy yourself. Yes, it might be because of jealousy and fear of abandonment. I personally wouldn't worry on the amount of validation. Do what feels natural to you. People with BPD have difficulty managing their emotions so small things can swell into big things. More important and controllable is to not be invalidating. It's up to you on what to do. I would probably take my uBPD wife to the side and ask what she wants to do. If she wants to leave then I'd probably be ok with that but go by myself next time.
