Does my ex want me back ever?

It is difficult to determine whether or not that person is interested in giving the relationship another shot. Honestly, I don't see the point on you wasting your time with your ex-girlfriend, simply because her leg was touching your leg while the two of you were having dinner at a restaurant with some friends. It's best to move on with your life and find someone better than her. I understand that you want your ex-girlfriend back, but if she isn't interested in getting back together with you, then don't push the issue. Good luck and you deserve better.
