Yeah he meant you look frumpy and dishevelled, cheeky git. It was not a compliment! 
It's like when people say 'you look different;' it's never a compliment.
He means you are not physically appealing to him. What a twat.
Let him see what he looks like after being in charge of house and home and 2 little kids, and all the domestics for several years. Cheeky arse! I am fuming on your behalf!
Thing is, when your kids are grown, you will be have a bit more time to yourself, and will look fabulous, sexy, and well presented (not that you're not like that now at all, just that you will be like that MORE!
)
Him however, HE will be a portly balding fecker, with a hairy back,who gawps at beautiful women who wouldn't give him a second glance.
Also, to say not doing/washing your hair for 2 days is wrong is a joke! I wash mine every 3rd day. I do shower daily though, coz I'm a smelly fucker if I don't.
I'm a bit chubby, going through menopause, and I've always been someone who gets hot easily...
I only have 5 min showers half the time though..just to get the sweat off. What a tramp I am aren't I? Can you tell I'm a mum! 
For the record, there's nothing wrong with 'doing yourself up' every day/washing your hair/putting your slap on/spending half hour on your hair,' if you want to or have time. There is also nothing wrong with NOT doing it if you don't want.
However, re the comments by @SoCallMeMaybe 'if you are messy, you cannot complain when people CALL you that!' Why the hell do you think people have the right to comment on how someone looks? And I bet people (including the man who said what he did to the OP) wouldn't say the same comments to a man!
And of course there is nothing wrong with looking like a mum, but this (rude) A-hole meant it as an insult. That is very clear.
