Out with a girl I'm dating and her married sister this weekend. Sister is a model and she was hammered so, naturally, she was getting hit on all night. She hit it off with some guy and she went home with him.
Her husband saw some texts and an uber receipt to some random address late at night. She gave him some bullshit story and said I would vouch for her. I don't know the husband and I barely know the wife. My instinct is to just ignore his calls but the dude is relentless. Do I lie for her or blow up their marriage?
