NDH, my hubby is very logical too, BUT thankfully his logic says that my emotions WILL be over the top and up and down because of the hormones so there's no other logic needed! He doesn't know WHY I'm crying, he can't understand it at all, except that it's hormones. He knows there doesn't have to be a reason except hormones. lol!
I actually explained it all to him early on, he already knew about it, but I explained to him anyway; my emotions WILL be everywhere, I WILL cry at nothing! I will be mad at you for nothing too. Please don't take it personally, it is only the hormones! Give me a hug and say nothing, and in 10 mins the tears will be gone and all will be well again. It works! If he tries to ask what's wrong, I get mad cos there's usually NOTHING wrong and I feel dumb having that pointed out. If he asks if he can help, I get mad cos I KNOW I can do it myself and don't want to be helped. If he hugs me silently, I can snuggle in, feel loved, sob my heart out for a few mins and be over it. lol! He doesn't understand it, but he knows he can't (hell, I don't understand it!) and it works, so that's all we care about!!!
And yay NDH, you're getting closer to testing, cos I'm sure AF will keep away! lol.
