HopefulDad,
Sorry to hear about your situation. I cant even imagine if we had gotten married how much pain I would feel. I know in the long run we will both be better off but its hard to look at things that way now.
It is hard and I think that's a big reason why so many stay with their pwBPD. Yet there are threads like, "Would you do it all again with your pwBPD if you knew about their BPD in advance?" and those same people who stay say "No way!"
If only our head and our heart could be on the same page.
