That's not a way of detaching. All it does is attach you with someone else that you fully can't commit to if you're still wanting to get back with your W.
"I am wondering if dating others could potentially open the door to a second chance with the understanding that we need to make other changes for our relationships to work in the long run."
Of course it can, but then again so can anything else like making friends with happily married couples or reading a book on how to have a great marriage, etc.
"I didn't mean to focus this thread on dating others and jealousy. That is just one example of something that can lead to attraction."
That's more jealousy than it is attraction. Jealousy is the idea of wanting something that you feel is yours. It's based on pride.
"I am currently dating my w and nobody else."
I thought you were going out on dates?
