In just ignoring her sarcastic comment is a baby step towards a bigger boundary for you. I think it would be very hard for you to setup a boundary completely shutting out all negative communication. By disregarding her sarcastic wit and not responding is actually a big step for you towards a bigger goal of limiting that type of communication. A few months ago you would have attacked, cried, or came here tweeting like a bird.
The more time I spend here, the more I have come to realize that divorcebusting has very little to do with saving marriages. It does lead down that path, but the true intent is not marriage saving. It has more to do you with saving yourself with the added benefit of leaving the door open to a possible reconciliation. Were as a majority of people go about this with a f@ck u attitude which basically guarantees the demise of the marriage. Using the techniques you open up yourself to accepting the actions we have had on ending our relationships. Coming to grips with these actions and finding ways to improve ourselves. There are also other insights, but for the most part this is all about us.
Going a little dark is much better than the F U attitude. Even if you don't reconcile, you are both those children's parents and that doesn't change. Someday when one of the kids gets married...I would rather be there happy for my child than be looking at my wife thinking "F U"...because that is where the F U attitude will get you in the end.
The only thing to regret is never trying....whether things go good or bad, at least you tried and from that you will learn.
