My boundaries with my wife(before she left me)would not allow my wife to have any sort of a friendship with another man who are not family members.I don't talk to other woman unless I have to for strictly business reasons so I feel my wife should give me the same respect and not try to talk to other men unless they are family members.I don't allow her to text another man unless they are family members and I don't allow her to email another man unless they are family members like her brother,her dad,her uncles,her brother in law,and her cousins.If they are not related to me or my wife,she has no business talking to them unless she has to because it's part of her job.She belongs to me not another man.If my wife were to be more than business acquaintances with other men outside of family members,I wouldn't be pleased with it.My wife can have female friends and text and email other people who are female but I wouldn't allow her to text or email another men outside of family.I think it's good wisdom not to have opposite gender friends if married.She can make many more female friends if she wants to.Far as my son he has no business keeping in contact with this teacher at all because she's married.I keep telling my son that it's wrong for him to email this teacher because she's married and he's a male.My son has no business communicating with this teacher at all since she's married and he has graduated and my wife has no business of having male friends.Would you allow your spouse to have opposite gender friends?
