It isn't usual to hear the kind of things that your ex is saying to you. Maybe it would be worthwhile to actually talk straight. If reconciling with your ex-W is something that you want, then maybe you do need to have that discussion. Since you are divorced and you are both in relationships, beating around the bush doesn't cut it. I would consider what she has said to be subtle clues that she considers you a good guy and possibly wonders what it would be like to try again with you. But that's just speculation. The only way you can really know what she's thinking is by asking her. If she shoots you down, then I guess you won't have to wonder anymore whether she's interested. It would make it easier to move forward (and away from your X).
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
