I have read so many posts where the NON starts to think they are the crazy ones or are at fault for the craziness that comes with being in a relationship with a person with a PD. Nope!
I just started dating a sane woman and was instantly reminded that the relationship I was in with my ex with BPD was far from normal.
In my new relationship, there is no self-made drama, mood swings, huge red flags, lying, walking on eggshells, etc. I too had questioned my responsibility in my failed relationship with my exBPDgf, mainly because my ex was very good at twisting the facts and laying the blame on me.
Remember, people with PDs are very skilled at making you the villain. Often times, nothing you have done or could do would change their behavior. When you date a somewhat sane person again, you will instantly see the light.
I have only gone on a few dates so far. It was strange at first and now I'm like wow this is what it is like to be in a normal dating environment. It had been 2 years. I had forgotten.
