My advice is to date these women. You don't have to be exclusive to just one until you are sure which one you like the best. I know it clouds the issue with your ex-W, but you are divorced and you do need to move forward with your life. Your XW's wants, considerations, and what she is going to do are things you can't control. She has to do that.

In the end, it's not the years in your life that count. It's the life in your years.
Abraham Lincoln

It is hard to fail, but it is worse never to have tried to succeed.
Theodore Roosevelt
