I hear ya, Smom on the Israelite/bitter water message. I had a similar eye-opener during some marital problems of my own some years ago. The things I wanted from my husband? Deeper involvement, daily conversation beyond the mundane, a passionate pursuit of our relationship, a listening ear, a willing heart, not taking "us" for granted, etc...were the very things that God desired from me in my relationship with Him. 
Man, talk about a wake-up call. I couldn't honestly say at the time that I was giving Him these things, either. That rocked me; made me look, with a very clear eye, at my relationship with Him. Changes were made. I began to actively and daily pursue my relationship with God. And today? BOTH relationships, with God and with my husband, are made of much stronger stuff. Taught me to work on my foundational issues with God first, then this would overflow into my other relationships.
