There is a difference in having a picture and the real thing. Be attentive to your husband, especially if he has no idea of the conflict this other man causes. If the "friend" comes to your home, disappear. Do not create a scene. Do it each time he comes. He is visiting your husband, not you. Say a hello if you must but leave the room like a good wife. If the friend knows you are attentive to him, he will continue coming for your attention. He is your husband's friend. This is between you and that guy. It is a silent battle for the sake of your marriage. Maybe you and your husband should start dating or go shopping or go visiting on the days and times the friend usually shows up. Keep a calendar and write the time he comes and goes. Put off shopping or the laundry for those days and nights. The friend will soon stop coming. If he keeps asking your husband for you, hubby may wake up and ask him why.
