What do you think about me telling my husband that he needs to stop snapchatting his coworker?
Why would oyu need to tell him that. Is his snapchatting a problem?
They coworker is clearly lying to him. One time he claimed to have one kid and now he says he has 3. He can't even keep simple stories strait.
I think it's okay for you to think that certain people that your husband is communicating with may seem not trustworthy. But instead of you saying that they should not communicate with this person anymore, I would recommend that you list all the reasons first why you think that that person that your husband is communicating to may be untrustworthy.
I'm not too worried about just telling him. My husband usually listens to me.
You should definitely let him know since it's making you uncomfortable, but you should really explain why. Even if he usually listens to you, he might get upset that you just told him to stop talking to someone. It's also a bit controlling to just tell him to stop without giving a good reason.
