I wish I didn't have to convince him that spending time alone with his hot wife is a good thing, I wish I didn't have to convince him that he's lucky his hot wife still wants to spend time alone with him after being together for 16 years (I'm 33 and we started dating when I was 17). I wish I didn't have to remind him that he takes our marriage for granted. But to dwell on what I wish wasn't so, doesn't get me any farther ahead....
I know what you mean. It's easy to think to yourself that he should be "getting it" and if he's not, then you're right and he's wrong. That you're a great catch and he doesn't appreciate you. And it's all true, but it only solves a very small problem: it tells you who wins. But you don't just want to be justified, you want to be happy.
I'm nobody's hot wife, but I had the same thoughts and often still do. "Does she just not understand how lucky she is to have a man who loves her as much as I do? Does it count for nothing that I've been through all the ups and downs, all the chaos, all the hard times, and I'm still here and trying to show her that I love her?"
It sucks to be taken for granted. The trick is in what you do with that. Is it a good excuse to get out? Or to get back at the love of your life, so your favorite person in the world can be made to suffer as much as you did? Or is it worth it to change the marriage?
