DH has a 'work wife' who, to say I'm not a fan of, would be an understatement. They carpool to work despite her living 10 miles in the opposite direction to his works and adding an extra 45 minutes each way to his commute. Last week was DH birthday and he brought a birthday card home signed by everyone. All totally innocuous apart from her message which didn't make reference to his birthday but simply said 'luv ya lots'. Am I right in thinking this is inappropriate and totally disrespectful to me and our marriage? It almost feels like it's a passive aggressive attempt to piss on her territory? Imo you don't write a message like that on a married man's card unless you are looking to cause trouble. Or is it completely innocent and I'm overthinking it?
