Your gorgeous girlfriend has never been very affectionate, so it hardly surprises you that she's been ignoring you all day. But when she comes into the living room wearing a tiny glossy red dress with her black bra showing, you're left confused. In a dismissive tone, she reminds you that she's going out to dinner with her coworker tonight. Watching her fix her makeup and dress so seductively, you can't help questioning her and complaining. She isn't hearing it, though, and makes it crystal clear that it's only a "work dinner." It isn't as if she'd be going out with you anyway, so she doesn't know why you're even upset. God, can't you just let her have fun? And because of your completely irrational jealousy, she's not planning to come home and won't hear another word from you. You don't really have a choice except to apologize and try to make it up to her, but you know exactly what she'll be doing tonight.
