Tuckerville, I'm sorry you and your DH had a fight. As for the IT band stuff, have you considered whether your crank is to blame? My Campy triple caused me to have IT band issues in my right leg. Its q-factor (a fancy name for its width), was too wide for me. I switched to a compact on my new bike and, voila, no IT band issues. Just a thought. It's a fit issue for a lot of women that I don't think gets much press.
Limewave, I am really sorry about what you're going through. It sounds like you and your husband have some signficant trust issues to work on. Have you considered couple's counseling?
Live with intention. Walk to the edge. Listen hard. Practice wellness. Play with abandon. Laugh. Choose with no regret. Continue to learn. Appreciate your friends. Do what you love. Live as if this is all there is.
