Thank you for the advice... .It's funny to me, when I think, or hear things like that (about trying not to make it worse)... .it always makes me pause and ask myself... .Do I WANT to stay in a relationship where I have to spend so much effort on trying to not make the situation worse?
Honestly, the tools you learn in staying are great for everyone. BPD is very real mental illness. Your partner has already had a lot of emotional/psychological stuff to deal with and having BPD as well makes it just the way it is.
Steph, great stayer success story - fully had to realize that once her partner was in DBT and getting better, she still had some pretty big stuff of her own to work through. I know you might not see your own issues that have led you here, but stick with your own therapy and work on your own side of the street - all relationships take 2 people.
For the record, I worked hard at the staying stuff, but my own resentments and my own needs made it really tough for me to have the patience necessary - but I also did not find out all this stuff in time, we were already in a very downhill fast moving situation.
