He has a habit of really playing down the little things that I sometimes have to do for/with the kids. Such as dropping off forgetten lunches/PE kits/Swimming bags, party drop offs and pick ups, bathtime when combined with nit combing 
, etc. "Well it only takes 5 minutes..." actually no it doesnt, as I have to get the baby out too and we all know how long that can take! And nit combing takes an hour per child as they all have v long hair.
But when he does any of the above himself, he wants the Victoria effing Cross! He does it, and will often offer to do it, its nice that i dont have to ask. Its the fucking martyred air he takes on that drives me up the frigging wall, that and the fact that I am a SAHM so he never has to take the baby with him, just grabs his coat and off he goes. Oh and bringing it up in a row, until I point out that he isnt "helping me out", we are a family and therefore everything is 50/50 unless he counts me cooking his dinner or doing his washing as helping HIM out. Funnily enough, he always backs down after I say that! When he does the martyr bit I say back to him what he says to me "oh but it only takes 5 minutes!" with a wry smile so he knows I am taking the pee, but really, it does bug me.
But my perception is a bit off as we have had a bad time in the last 3 months, so if I am over reacting then I would appreciate being told!
