My ex and I really haven't got a long over the last couple of years. She broke up with me a couple years ago. We work together and last year hit kind of a low when I had to move stores. This year I got to go back to my old store with her. And lately since I been back we have been getting along. When we talk she is calm and not rude or anything like that. We had nice conversation today about her vacation. Before she left for vacation she was doing gate duty at work, we have someone open and close the gate to make sure no one else comes in at the end of the day, and I was leaving and I thought about waving to her but I don't know if I was going to but she waved to me first with a smile. I'm trying to figure out if she is being nice to me because we work together, she wants to be friends again or still has feelings for me. Thoughts?
