If your Husband is joining his colleagues for Bangkok trip, and haven't tell you about it, tickets and hotel (suite) booked. Will you allow when he mention to you about it? How would you handle it. It's all guys trip.

I will be upset. But i let still let him go too. I will get him to update me and find out who are the male colleagues that are going with him. everyday check on him. (rather then sound like it's stalking, you say it's more reporting safety)
