I read your request earlier and then came across this article (at the bottom) and thought it was something that might help you. Hopefully this helps you explain to him that while you like to do everything that you normally would, you still need more help from him in other areas. Aand that by having the extra help you will be less likely to be moody (iffy with you being pregnant, but possible) and less exhausted most of the time.
Another sneaky option would be to let him take care of everything for a day or two and arrange for you to go away for a girls night or weekend. Prearrange it and say you would like him to walk in you shoes for a day or two. The only thing that you can't have him expierence is being pregnant unless you rent one of those sympathy bellies. But this could backfire on you if you don't talk about it first.
The Hunter-Gatherer Difference
Have you ever noticed the difference in the ways men and women talk? As women, we like to explore, analyze, and discuss our conflicts, often nodding and completing each other's sentences. But if you interrupt men while they're speaking or overload them with information, watch out!
This difference is a byproduct of our evolution. As "gatherers," our prehistoric female ancestors survived by multitasking — tending to the children, stoking the fire, and developing social bonds with other women all at once. We thrived by being mentally complex. Men, meanwhile, were the "hunters," focused on a single goal — such as driving the bison into the ravine, killing it, and bringing it home. Thinking about anything else could have been a fatal distraction.
Our cave-dwelling days still resonate in how we communicate — and argue — today. So when you want to hash it out with your man, focus on the solutions. Instead of playing the blame game or delving into endless details, approach the conversation with a sense of what you want him to do. Communicate requests like do the dishes, put the kids to bed, or touch me like this in a way that's respectful, but direct. Also, be sure to say what's bothering you, instead of nagging or, worse, brooding and never saying anything.
Show your man that you can talk to him in his language — and he just might surprise you by speaking back in yours!
