Hi T.,
First off, I know just how you feel. My husband and I have been married almost 17 years, and this has happened several different times during our relationship. A few things are triggers for us... #1 was pregnancy and nursing. Are you breastfeeding or did you for awhile? This "pause" in sex drive is sometimes closely related to having a little one. It is sort of natures way of keeping you from becoming pregnant too soon, per-say. It doesn't happen to everyone, obviously.
#2 was stress, or resentment... I often felt like I was spending so much time carring for my little one and he wasn't helping as much as I thought he should. This resolved itself as the baby got older and required less of my time.
#3 was plain EXHAUSTION! I work a lot, so does he. We both colapse into bed every night and forget sex. He would say I didn't like him, or didn't find him attractive anymore. We started having more "morning" encounters, and that helped a LOT!
If these are not the reasons for what is going on in your life, you may want to talk to your Gyno about getting your hormone levels checked out. Are you having normal periods? With normal ovulation?
Sorry this is so long winded, I hope you get it all figured out soon. I know it's no FUN! Pamper yourself a bit - it does wonders. Get your nails done, have a pedicure and/or a massage, a new hair cut, or color....
Take Care,
