Has anyone been dumped after being diagnosed with PTSD?

I’m asking because I have been. My now ex broken up with me because I changed.

When he told me he was leaving me I had emotional breakdown. I had to go to hospital.

Why I’m asking because He been out my house for 2 weeks and I don’t feel anything. Just confused when I think about him. I feel absolutely nothing no sadness nothing. I’m seeing a therapist on Tuesday to talk it through understand
