Sweet that you want to take the 1st step to resolve your issue from the weekend, considering he was the one being moody. It's hard to be the grown up. Sometimes it gets into a "im not going to blink 1st, game of relationship chicken." Do you have any idea what caused his troubles inthe 1st place? Was it home or work related? Is there any possible way that you were being moody too? I only ask because you haven't had a break from the kids in so long, noone could blame you for being tired, cranky, frazzled. Maybe he was feeding off your mood? Or maybe felling neglected because the kids get so much of your energy?
Probably hasn't even occurred to him to celebrate the 1 monthiversary. And, If he was being moody because your cycles have lined up, maybe quiet time on the lake is just what he needs to clear his head.
In any event, your dinner fell through. What to do now? You can't make him a nice dinner, but you can pack something great for him to take with him, along with a little note or a card. Quiet time on the lake is a good time for reflection, so, putting your feelings onto paper should go far.
Next thing is how to get you a break from the kids! Can you enroll them in Vacation Bible School or drop them with family or something? You need to recharge your battery so you will have enough left to give.
