Hi DevilYouKnow,
I found these work related dramas good opportunity to coach her a little on boundary skills. In the end it is her job and her decision and I try to be careful not to slip into problem solving or taking sides. But where I can help is showing who owns what, what other parties may feel and alternative action paths that are not obvious to a person that tends to dive head-first into conflict.
What is putting my guard up right now is she is saying she should quit to tend to my PTSD (I am a five-time combat vet diagnosed with PTSD and major depression). I have been painted as the crusher of her hopes and dreams and career enough times that I am wary she is lining this up in her mind as an excuse to quit without blaming herself.
Is she walking on eggshells? If she is - and remember her perception is the judge here - then that is not good for your relationship and is also adding to her emotional base-load making her more unstable. You are certainly in a bind here as you do have real needs due to the PTSD. You as a couple have here a lot to cope with and the best you can do imho. is to sort the issues and place as many as you can as close to the person that can effectively deal with them: Her the BPD and you the PTSD. PwBPD have often weak boundaries and she may well be perceiving and maybe carrying more than you want her. Clarification and prioritization of your needs may help her to give you support where you truly need it and feel less burdened by stuff she can't help with and you have to carry .
