If you ever figure this one out, let me know! I think all relationships tend to go through these ruts, especially once babies are in the picture. It's taken 2 years since we had our last baby for our sex drives to even come close to matching, and I'd still say that I could use it a heck of a lot more. I seem to be way more interested than he does.

Really, @indiglo is right. You need to sit down and talk about it. Not talking about it just makes things worse. I remember going over to my Mom's and bawling my eyes out because he didn't seem to want to have sex and certainly not the kind of sex I wanted to have. It was horrendously depressing for me. (Note that I have also not gotten back into shape after four babies...)

But really, it could be any number of different things. Maybe he's just tired, maybe he's not getting enough of some sort of nutrient in his diet, maybe sex just isn't on his mind. You'll never know unless you ask, though I can't say that this will solve everything. But at least you'll know how to navigate better.

I wish you luck. And just remember, you are most definitely not alone in this situation. I feel the same way you do!
