If your spouse travels for business – it’s normal for you to know where they are traveling to. Often they will be traveling between two cities where their company has an office. For example, between the NY office and the LA office. However, if your company has no such offices, and your spouse doesn’t have clients in certain cities, but they are always traveling to those same destinations there may be something suspicious going on. Also – if they can’t explain why they are going or the trips have erratic dates (such as weekend trips), they may be traveling to cheat on you.

Normally people  use credit cards when they take business trips. If your significant other suddenly wants to pay cash for everything on their business trips – they may be trying to hide what they are spending their money on.

Does your spouse travel for business? Have they started traveling for business but they haven’t been promoted? Are they traveling to Vegas for work but they don’t have an account in Vegas? Are they traveling to cities where their company doesn’t have offices? If you see your spouse traveling without any justification, they may be maintaining an affair.
