I see quite a few positives in your situation. Honestly, I have to fight the urge to smack my wife's "booty" lately. From my perspective I find myself wanting to do it when I'm in a good mood and feel warm and friendly towards my wife. Besides the fact she has a great booty. I'm not sure if your husband feels the same, but I would guess he isn't far from it.
Dinner, laughter and good conversation without the kids is a date. It sounds like your date went well. Take it day by day. Relax. Let go of expectations. I told John that he has to stop being a yo yo and you need to try as well. I know it's hard and I think detaching in general is the hardest thing to do right. However, it's for your own good. It doesn't mean you don't love them and don't care. It means you love yourself and care about yourself.
I'd be positive if I were you. Don't let the little ups and downs get to you. Look at what we finance dorks call the trendline. It eliminates the noises of random events. Is it up or down? From what I see, yours is up.
Thanks for the kind thought earlier. I hope you have a good week as well.
