I'm on your side on this one. I couldn't do it. My (ex) husband went to Canada for 9 days with 2 girls and didn't even tell me about it (I was in Michigan, he was in Boston), couldn't figure out why I was panicking when I couldn't get a hold of him, saw absolutely nothing wrong with it. NOTHING. Then brought one of them into the house to "mingle" a few months later, after we got housing and I moved out there. To this day he will tell you there is nothing wrong with it. If she is going out with a mutual friend, someone you trust, maybe. She is married to you. I don't see it being acceptable, not with her history.
