Husband and his female co worker?

Well what was his reason for lying about her not working with him? I mean why would he even say she doesn't work with him anymore, that's pretty odd and he's definitely hiding something if he lied at all about anything! If he hadn't of lied about that then I would just say you were over reacting and that they're probably just work friends, but if there's a lie involved then someone cannot be trusted. You don't lie unless you are trying to hide something!
