Can anyone answer this question?

Please forgive my ignorance. I’m very unfamiliar with Tarot.

My fiancé is an empath. He reads tarot semi-professionally and seems to be dead accurate with his interpretation of the cards. However he WILL NOT read for me. And he won’t give me a reason. I don’t push, I just let it go. Is there a significant reason you shouldn’t read for your SO?

Thank you in advance.
