Hi JustDessert,
From there we began texting each other several times a week, again all amicable and it felt good. At no point did i harbour thoughts of returning to the relationship. A few months on from there came a rather out of the blue text stating that she didn't want to hear from me again (the actual text wasn't unpolite), this knocked me a bit
I'm glad that you decided to join us after having lurked for a while. I can relate with having the first partner I cohabited with was an undiagnosed pwBPD it was intense. It would knock the wind out of me too if I were you, I understand that you don't want to go back going from a romantic r/s to a friendship you might some lingering feelings for her?
