When I started dating my now DH I didn't feel compelled to share my entire history with him - I mean that was the past.
DH expressed a strong dislike of drug use so I never mentioned that I used them in college - again, this was the past - I met him 7 years after college and I didn't do them anymore so why tell him?

Anyway a few months ago the cat came out of the bag - he was pretty mad about it - its fine now though. He asked me if there was anything else he should know - I told him I was a stripper too!

haha j/k

anyway.... does your SO know everything about you?
