I totally get what you are saying about being friendly vs freezing her out. I have debated this question on my thread recently and thought about it a lot. I agree with vossy in your case since you have children you need to remain cordial for their sake. However, on top of being friendly for the kids, what else do you do? I get the desire of wanting her to hurt as much as you do, of taking away your friendship to hurt her. I am questioning the same thing and I am constantly going back and forth on this.
Would it make her miss you if you take your friendship away? Yes, probably. That has happened in my situation. But then what? Once she misses your friendship then what do you do? Do you then be friendly again because she missed you? Then she won't miss you anymore! Argh!
So I say be slightly friendly and continue to show her how incredible you are. Show off that PMA and 180s! But don't give "extra", just be friendly neighbor and let her pursue your friendship.
