Guys, If a man says you are forbidden fruit, what does that mean?

Anonymous
I thought I'd ask a again bc I didn't get many response. So here are the facts:
'He is in his 40s me early 30's.
He has never been married or had kiddos.
I am not a virgin and to my knowledge we are both single.
He told me that he did not have a desire to have kids or marry, (at this point we are just talking)
I told him that is his business but we could obviously only be friends because I wasn't sleeping with him. I told him if he never wanted to speak to me again, that is fine bc I don't want the pressure of him trying to convert me or vice versa,

Guys What do you think now?
