OP, perhaps start texting when she comes home a very PA "X mentioned that she asked to FaceTime me again but you didn't. Could you please do this"?
Yes, I definitely will do that. I like that wording as well, matter of fact and no emotive language, which I struggle with!
@FantasticButtocks I know you're right- I suppose I'm just used to operating in this way and hopefully in time that will become less of a habit. I do want her to feel that she can FaceTime him at mine though, for her own benefit, so will keep offering it at now and then opportune moments.
@Mix56 argh, I really struggle with the idea of not looking after her when she's sick. I know he'd take decent care of her, but who doesn't want their mummy when they're ill! Again, I suppose this is another thing that I will adjust to with time.
The good news is that there was no sickness bug from her so phew! We had a gorgeous day together yesterday- being separated from her really does make me appreciate every minute when I have her, which I suppose is a plus side (previously I'd sometimes be counting down to bedtime for some peace, which is awful to think back to now!). She's at his this weekend but I am off to a friend's tonight for a dinner party then will spend this weekend getting a head start with her bday and Christmas presents 
Wishing you all a happy Friday and lovely weekend!
