I work work with my ex and i told her i give her space and I did the last two times I worked with her. And when she left and waved to me i thought she was going to do a regular wave but she wiggled her fingers. I worked with her to day and complemented her on what she was doing and she said thanks but it wasn't a mean thanks it sounded like a sad one but I don't know. When she waved to me today she did a regular wave. I don't know if she was mad at me for talking to her or of she is playing games.
