I hate using the term OW in cases like this...it doesn't apply.
Ping...regardless of what your wife said today. You realized that you don't have the right feelings for this lady.
If you don't talk to her like Ian suggested, and others as I recall...then our similarities end.
Be a man, not a boy.
If her feelings develope deeper for you, and you hurt, knowign you would drop her if your wife called up and said sincerely that she wanted to be happy with you...man...that's cold.
As for your other thoughts, yes agree, and understand them.
