My husband has been caught in the past for cheating. Lately I've been feeling strange, as if he's doing it again. So I've been checking his phone and I've seen his chat log. He has mentioned how they had plans to marry each other if they didn't end up with anyone. He said if he was single he would have sex with co-workers and the girl he's chatting with. He asked her for her office number. What should I do?

Insecure?? His infidelity is staring you right in the face on his computer or phone, right? This is now, not in the past? File for divorce. Start salting some pennies away immediately too.
