Well, my wife goes on trips like that, and I gotta say I trust her 100%. But the stories they come back with make me jealous and horny at the same time. They all get hit on a lot, they say, but confess they're totally faithful. My wife loves to tease, but she'll only do it with a big crowd of her friends around her.
I know she dances with other guys, and they've got the wrong message sometimes. Like she says, "I know who I'm going home with."
Should I trust her? Well, let's put it this way: her first husband was a cheating bastard who had three different affairs at the same time while married to her. She kicked his sorry ass out, and it's taken her a long time to trust men again.
But she certainly can trust me, and I'm gone longer than she is when I'm on the road. I'd never do anything to betray that trust either.
