Sounds like you're doing well. Keep it up...keep flirting and lookin' good, cause it really is the best revenge!
Last night I went to my kid's field hockey awards banquet, and a lot of the single mom's made it a point to come sit with me or say hi. One even offered to bring me some cake...word gets out that a great dad is now single and the ladies are lookin' to den up for the winter. LOL
I would suggest taking a long break from contact with your ex. No emails or calls unless it's a TRUE kid related emergency. Give her some time to miss you, wonder about you, and create some mystery in her mind about you. Get out there and date too...just meeting a lady for coffee is great practice for later on. Yahoo personals is fun. I met my current gf there (and she's a high school classmate of mine!)
Stay strong!
