Is she right to be worried?

I feel really sorry for guys like you. I cannot believe that people can be so unreasonable. Your wife's behaviour is just not right. The fact is, you are giving a work colleague a lift to work!. If your wife carries on like that, she will drive you into the arms of another woman who is not quite so unreasonable. Honestly, tell her straight you are happy but do not pander to her - that is what jealous people want and in the end, it will grind you down. It's also a bit worrying how many people ar on your wife's side! I am not - she is totally out of order and needs to grow up.
