I’m not sure this is the right place to pose such a question as I am in an extra-marital affair with a woman whom I love deeply but one who has BPD. It has affected our relationship to a point of exhaustion and I must try to leave this in one piece. I also want to make sure her emotional-well being is preserved as she is not in a particularly good place at this time. 

This is affecting my life in ways I never imagined and I am feeling despondent about the way it has unfolded. 

I don’t know what to do.
