Your Evian water bottle? OK, Princess. The fact that you drink spring water at home and feel the need to tell us the expensive brand already gives me an idea of the type of person you are.
I don't agree with some people who think your husband shouldn't have had to ask permission to go out. You're a team with children and there should be a discussion whenever either of you wants to or needs to go out. You would be unreasonable never to agree to him going out though. (And he would be unreasonable if that was very frequent.)
But given that you had agreed that he was free to go to the event last night, you knew that you would be the one on call with the kids. Yes, you're pregnant and not feeling well, but you're not the first woman to ever be pregnant, and you chose to get pregnant with a third child when you already had two children still young enough that they wake you in the night (to pull up the covers? WTF?) and get up early. You should have sucked it up and made the morning as easy for yourself as possible, until your husband was up and ready to engage. In a marriage that's not dysfunctional like yours is, I would expect your husband to take the night shift and the early morning wake up the following day, or maybe even the next couple of days, in return.
Obviously, though, this is a dysfunctional marriage. He should not have sworn at you and especially at the kids, no matter the circumstances. But even more so, I believe that you squirting water on him crossed a line. The only time I think n action like that might be acceptable would be in self defense, which this was not.
It's a shame that you are bringing a third child into this relationship when you can't cope with the two you have. But that is the situation you find yourself in. Couples therapy could be very useful, so that you and your husband can try and learn to treat each other with respect. Otherwise this is not a good environment to raise kids in.
