I completely agree with hopeless...try so hard not to check out his myspace twenty times a day (I did too!). It just hurts you, and provides nothing constructive. Myspace can be so dangerous (it's how I met my OM).
The IL thing is so familiar too. My MIL and most of the family didn't like me much to begin with, and my affair pretty much blacklisted me for life. (So much for forgiveness and their religion, eh?) When your husband finally comes home, make sure that you work on repairing the family situation too. My mom told me you don't just marry a man, you marry his family too. How I WISH I had paid more attention! It's so wrong that they prefer her to you (grrrr!); is there anyone in the family you're close to who could be your ally?
