Blimey, I didn't think this would kick off in the way it has - it was more that I wanted to get it off my chest and didn't feel able to in real life. Having posted in haste and reflected at leisure, I think jealous was possibly the wrong word to use!
I don't think that my dh wants to shag the au pair
I don't think that she is in any way interested in him in that way, either.
I do feel irritated that he has time for ds at the moment that he wouldn't normally have, but that could well be due to not wanting to be seen as being a crap hands off type dad in front of someone else. Actually, me and dh were out with some friends last night and he was fussing about me getting my feet up etc in a way that he doesn't do at home, probably because friends were commenting on how uncomfortable my legs looked - back to the not wanting to look bad in front of others!
I suppose I have always been a person who just gets on with things, so I don't ask for help. Over time, dh has obviously come to the conclusion that I don't want or need any, so doesn't bother to offer these days.
I'll keep an eye out over the next few days for things that make me uneasy and bring them to dh's attention - because if I don't tell him, he won't realise. And maybe I'm just feeling a bit sensitive because at the moment, ds wants to do things with the au pair rather than me - possibly the novelty factor and the fact that when he asks her, she says yes of course and does it, not 'in a minute ds, I've just got to do x,y,z first'
Like I said earlier, bringing someone else into your home gives you quite a brutal insight into your family dynamics, and I'm sure that would be the case however attractive or otherwise that person might be.
