hey man been there before. What I did and it worked for me is used the I'm divorcing you routine she replied almost instantly to it. If you don't know it go to
www.badboylifestyle.com its on there. It was just an issue of my 1st txt wasn't very creative and basically her thoughts were if you want me to respond you're gonna have to do better than that. However if that's what you decide to do and she doesn't reply I'd leave it be then when you see her at the bar go up to her with confidence and in a cocky/funny way open by saying I'm still waiting for you to sign the divorce paper jeez what's taking you so long?!?
The whole thing is a little cheesy, but I've never had that not work for me.
Anyway hope that helps good luck!!
