My ex-T ended things abruptly with me, too. What helped me was time, lots of crying and grieving, and processing it with T and then a little with L. It's been 8.5 years since she abandoned me. It was really difficult to trust anyone. For me, I had to give T some trust to work through it because processing it was the only way I was going to survive it. Thankfully, T was/is a good therapist and was able to hold my anger that sometimes came out at her. She even tried to get me closure with ex-T, but couldn't.

I have finally let go of the hope for closure from ex-T. Instead, I got my closure from T and L being good therapists, and processing it over and over again. They are my closure.
