JP...

The controlling thing is obviously a ploy... IGNORE IT.. ALL CHEATERS SAY THIS... ALL OF THEM

More importantly... when YOU OFFER to give him account info and he says "I trust you" he means "I want privacy so I can keep secrets from you"

You have to BITE that one RIGHT AWAY

When he says "I trust you"

you say

"This isn't about trust, its about us BOTH feeling SAFE... And I DON'T right now... are you going to HIDE things from me or are you going to make your life available so I CAN FEEL SAFE in my OWN HOME?"

If he says no to putting his account info on the table you have your answer.. he's addicted and you need to start playing hardball with him

You start YORU spreasheet NOW... Put it together and ask him to do the same... Don't NEGOTIATE or DEBATE the subject.. just DO IT and invite him to participate.. if he does NOT... again you have got your answer...
