It came to my attention yesterday that my ex partner often asks our son via text message 'what is your mum doing' or 'is mom napping'. Son is almost teenager so has his own phone, but turns out this has been happening most weekends where he asks. My son mentioned ah dad wanted to know what you was doing. Thought nothing of it until I checked my sons messages where it's every weekend for a few months. Or if it's at shool day he will ask "have you spoken to mum". Am I unreasonable to thing this is strange? Ex partner constantly messages me so I'm guessing if I don't answer him quickly he will just ask our son.
