Is it OK for my husband to go movies with another female?

Where are all of the open minded, guy friend having women? You can't stop him if he's going to stray. If he's asking you out loud there isn't a problem. When you stop hearing about this colleague you can start worrying. Until then, you should trust him as much as you would ask him to trust you. Or are you untrustworthy and think he is no better?
