I haven't posted on Websleuths in years, but this case hits very close to home for me. I am kind of the Heather Elvis in a similar situation. Fortunately, (extremely fortunately) things did not get this far in my situation. I made a huge mistake, and I live with that guilt daily. Still, I tend to understand Heather's perspective. However, I am also a wife, so I can see Tammy's hurt.
Heather is the true victim here, and my heart hurts for her family. My heart hurts for Heather for falling for Sidney. It's hard to control feelings. I mean, we cannot help who we fall in love with, and poor Heather picked the worst possible man.
I work in the legal field, and I have been following the trial daily. I think Tammy's attitude plays poorly upon the jury, but, IMO, I do not think she will be found guilty. I am disappointed in the cross of Tammy.
