Is she just a torchered soul who requires much attention or is it something that would have eventually happened no matter what I did or did not do?
If she does suffer from BPD, then chances are it would have happened regardless of what you did. I loved my ex unconditionally for the most part and gave her a lot of support, love and understanding in the beginning of our relationship ... .at the expense of my own emotional well being. This for the most part was not reciprocated, but rather she continue to emotionally hurt me, which pushed me away and I distanced myself from her and that pain. The more she hurt me the more distance it created and that really hurt the relationship. It is exceptionally hard to continue to be supportive when you are living in the FOG 24/7 and are almost constantly feeling some type of emotional pain. Every time I allowed myself to get emotionally closer to her I got burnt.
