Bonbon,
Personally I think what he did was wrong, especially since you really don't know him well. I would feel violated and of course I probably would have said, "What the heck are you doing?", a big fight would have ensued and one of use would be in jail. Thats the scenario in my mind, not sure if it would have happened though. At this point I would be thankful that he didn't take any money, as for relationhip with him, something you need to decide if you want it to continue.
Tinyone, you must be a much better self controlled person than most of us codies. I won't even go into my snooping with my husband. He is an alcoholic/drug addict and in the beginning I snooped a lot. Wallets, nightstands, basements, etc. I don't do it too much anymore but that is not saying it wouldn't happen again. I've learned to control myself a bit but sometimes the need to know supercedes common sense.
