Thanks ladies..
I think that is the case sometimes, but I also agree with what was posted easier by someone, and that it's also easier for them that way.
I have outright, for instance, told my elder brother before (who I used to be quite close to) that I wasn't happy, I wasn't being spiteful, but everyone is asking TOO MUCH of me to carry on through this, and that it was a mistake to stay, and was no longer what I wanted. He totally ignored me, said I was being childish, poo-pooed it, went on about what an amazing guy DH is (!) and basically made me feel like an idiot. His answer was to then suggest that I go out drinking with his gf (who I actually get on well with, not the point) that weekend 
I very much get an air of "I can't deal with this right now, haven't you caused enough stress already" from my mum.
My best friend doesn't know why I've not left already. Not because of the incident, but because I'm clearly just not happy.
I get little things all the time that make me feel like things are acute..he'll say something, or fuck up again in some small away (can be really irresponsible about stuff, and buries his head in the sand - for instance, took well well over a year to change the car after DS3 was born and we literally couldn't all fit in the car- to the point that the car ended up being driven in the ground and worth nothing but scrap, but if he'd sold it when he should have done, we'd have been able to part ex.)
Somehow, I'm the nag though. I am at work all of the freaking time. When he was the one working, and even before that when it was both of us working, I'd handle this stuff. I don't ask much in that regard. Sorting little things as I don't have the time/stuff closes by the time I get to work, and he just always seems to fuck it up.
I'm NOT a nag, I'm pretty laid back, but one can only take so much little let downs after so many major ones. Every time I get our head about water, he does something stupid and irresponsible, even if it's just smething like his recent car parking ticket.
And I know that none of those little things are worth leaving over. My point is that these little things just grind me down - I mention them, and he goes "right. OK. I'll sort it. DOn't treat me like a child" and I want to fucking yell DON'T ACT LIKE ONE THEN FFS, you know? And I get sooo resentful. And I know I'm resentful because I'm unhappy with him, and finding outlets, not because it's that big of a deal.
I dunno. Ranting now.
DS2 is also lay next to me on the couch. Has been puking up all day, bless him.
Everyonesjealousofgingers, hope baby isn't sad anymore :(
