Is this a good sign?

So, my ex broke it off 2 months ago. We have been in contact. We were together 10 years. She is/was seeing someone else.
She was upset the night before because the guy she was seeing and a bunch of her friends had plans to hang out but they ditched. She sent me a bunch of texts all night asking how I was and stuff, the first time she contacted me that warmly.
A mutual friend was in town and we went for lunch the next day with her and another guy. After lunch I went to her place and had a coffee. I slowly sat closer next to her, then rubbed her leg, then her back, then I sat directly behind her and rubbed and cuddled her she didn't stop me and seemed to enjoy it. All of a sudden she asked me to stop. We talked for another little bit then I left.
Is this a good sign that she is getting close to wanting me back? How should I procceed?

There is a difference between wanting somebody back than having somebody as an emotional tampon, after breaking up with a lover. Seems like you might have fallen into the friend zone, but I would wait and see because she was ditched by her friends, and fell down and needed that emotional support that you gave her. If she doesn't get back with that ex or anybody else, than you're good to go to try to get her back.
