I don't think there is anything wrong with it at all. I always text my boyfriend when I am going somewhere, or leaving for my way home. He does the same. It is just courtesy and it leaves both parties from worrying or having to guess at what is going on.

I have anxiety issues and I will jump to the worse conclusion, especially with bf, if there is no communication. Me and bf do it to head off any panic attacks I would have if that communication wasnt there.

Maybe talk to your wife and show her how this affects not only you but your daughter as well.
