Hey tammy
I know what it is like to be a loner and introvert, you feel so great when you have your PWBPD idealizing you. During devaluation you try so hard to make things work while being frustrated, hurt, and angry, finally you need to leave and the pain is excruciating. You must always look at the overall of your situation in life; better to be lonely (for a time) and in peace, or living the BPD rollercoaster from hell?
The thing is life wasn't bad. we never argued and I thought we would be together forever. He did have the tendency to blame everything on me and always complain n matter what I did but I just shrugged it off. It didn't bother me that much. I just blamed the prednisone that he took. We didn't figure out he had BPD until the end. It sounds weird but I was happy.
