Hi Delicate-Dove - you poor thing, having to do everything while feeling so horrible.
Maybe you both need to sit down and have a good chat about what happened. Maybe your DH has other issues which he hasn't spoken about. I agree with you that it was totally unjustified for him to watch you being sick without offering you any assistance. (they can be so stubborn sometimes - although in saying that, i know i can be too )
Hope it all gets sorted so you can have a nice evening together.
