*raises hand* Quite a number of people I am guessing, as I assuming that not everyone expects a woman to love the living symbol of her husband's infidelity and don't see that as being overly spiteful.

Bonus, we won't have to see Robb's character destroyed anymore either. I just re-watched the clip where he and Catelyn argue about his marriage and I ended it wishing she put him over her knee because he was being such a childish brat.

Aren't they try to keep Theon's location and fate secret? So showing Dreadfort would work to give that away.

She never sees him again. Additionally, she kinda gets caught up in this little war so she might have other things to think about rather how she needs to send him a nice apology letter.
