Bit of a weird one! My DS11 came home from his Dad's today and whilst updating me on his day said that his step mum (well, dad's girlfriend) had told him that a few years back she'd had a couple of dates with my boyfriend of a year. My boyfriend has seen her from a distance and has seen photos so knows who she is. Boyfriend has only recently met DS.
His step mum has told a number of bizarre lies before (I won't go in to that now) but I can't imagine why she'd lie about this (or tell DS for that matter but that's a whole other story).
AIBU to think if he has dated her previously he should have said something? It's all a little strange.
