You must have had a real connection with your x-t. Otherwise, you wouldn't give them a passing thought. What was the reason things didn't work out?

For me, it was because someone else directly interfered in my therapy. My x-t had no respect for me and was looking for some kind of adventure with the obnoxious 3rd party. He took from me, the 3rd party took from me and I am left with nothing but broken relationships thanks to them.
