Hi, I have no idea what your husband was thinking in giving this guy your phone number, or what he plans to do now that he has worked at his house. Maybe it was his boss who gave out your number. But whatever the reason is, do not just let it go. It is bothering you so you should talk to your husband. Don't go into the conversation mad, just ask what is going on and tell him about the phone call you got. Communication is the most important thing in a marriage and there should be no need to play games with each other. Especially when it is about a serious issue. Talk to your husband, be honest with him and hopefully you will get honest responses. Good Luck.
