lattie,
I'd like to add that after you have this frank discussion, try and remember that you have every right to set boundaries.
Right now he is saying you are lying to him; where is his trust in you?
Jmo, but there is a limit to what you need to share about your past experiences. It's your business, and yours alone. You decide what, or if, you are going to share.
It appears that honestly sharing with him is not helping the situation anyway...

Best wishes,
Cap
