"cure brings my death"

So I saw her at the airport after a few years of my "not meant to be" end.

She was with him,the one for whom she left me.

So there were three people related to each other like strangers.
No way to avoid as our flight was the same at least at this time.
I said,hi to them and wanted to leave,
He stopped me and said,"don't leave,she had told me all about you. "
"Nice to meet you."

I said,"nice to meet you both. "

Then he said,"I am a cardiologist, still I cannot cure matter of hearts"
I said,"I am a writer and cure brings my death."
