@Cheeseisneeded Stayed up till 1 am fine - yes. Not sure if it has anything to do with anything. OP herself says that it maybe contributed to him overall not feeling ok. But we can't know.. Maybe he couldn't sleep? Maybe he could have but was wasted his time, who knows? Whatever the case is, the next day he was ill. And he didn't choose to get ill to screw his wife over... nobody does that. Do we know if he would have gotten up if OP asked him to? We don't know that either, as it wasn't said. But no-no, he should just F right off for being selfish.
All I am saying is not everything needs to be a thing. And getting angry at someone for getting ill should certainly not be one of those things. Reserve the harsh judgement on those dickheads who gladly knocked their wives up, are away from their families all week being mega-important boys in suits only to then spend their remaining free time playing some wanky game, like golf... If my wife promised me a lie in the next day, but she feels sick, I get up, no problem, because I am not a one-dimensional simpleton who only sees the carrot that has been dangled in front of him, but understand the reality. Throw in the curveball of her potentially being up late watching youtube or whatever? - Guess what, same thing - DOES. NOT. MATTER.
"Mothers are seen as the default parent, they dont get to choose
Pregnancy nausea and exhaustion? Get on with it !
Cold but not so ill he stayed up until 1am and he gets to choose"
Nobody, not one person brought in the "mom should do it because she is the mom" argument. Also, "cold, but not so ill" - not really up to you to decide how ill DH is, I'd rather take OP's assessment. Also what the hell are we talking about when we say getting on with it? Getting on with what? Does DH have a choice in when he gets up to go to work, something their family relies on? When DH is at work, of course a stay-at-home-parent needs to get on with it, as there is nobody else to get on with it... In this situation when there are two parents present, but one is sick, of course the one that is not sick gets on with it. It is such a simple equation - and yes, same applies if the roles are opposite. non-sick parent to step in because that's the decent thing to do. Out of love and care, maybe, instead of "me me me, I deserve, not fair on me".
OP stated no calling in sick either. So maybe it is in everybody's interest he gets better by tomorrow, no? I guess not, as the lie-in was promised...If both OP and her husband was sick, I am willing to believe that the husband would have no issue getting up. We do not know, of course, but there's a good chance.
