So, say your husband/partner does the school run whilst you work. He's made a few friends up at the school, mainly people you are friends with too.
There's one of the other mums neither of you know, she's quite young, always very well put together (full face of make up, hair done, always in dresses etc) and your partner seems to have taken a shine to her, you've been told by a few different people that your partner always stares at her and has told her she's pretty and that she always looks nice on more than one occasion
Would you think nothing of it or would you suspect he fancied her?
