Only 2 things you can do now. Give it to her and kiss it good-bye or as quick as possible buy yourself a new toy. Either way consider it gone and start over (with a better hidding place). I once had a good size stash built up in a secret savings acct and yes the wife found it (6 grand). I turned it over to her and in a matter of a few weeks it was gone---spent on worthless crap that we didn't need like new furniture and appliances.
