First I want to say thank you to everyone here. I have learned a lot and I put it into practice daily. I would like to contribute a Little to extend the same help I received when I first started.
How this ties to getting your ex back. First read the posts here. They are helpful. I find that making a "cost-benefit" chart to be helpful in seeing if you really want your ex back. Second use the tried and true method. Ignore her will still remaining a gentleman. It really messes with their head. I personally got dumped a few weeks ago for reasons I don't want to divulge out of respect for her but I still remain cordial and chivalrous while flirting with other girls. It drives her wild. She texts me a few times a week out of the blue and the responses are instantaneous. Follow the "old ways" and prove that you don't need her to have fun. It works well.
I hope this helps someone.
and Good Luck
