Next dilemma,

Even though I have little or meaningful no contact with my W I do have to see her at some sports events that our S's take part in. My approach up to now had been to say Hi as i passed by and she was trying to ignore me as I felt it was kinda dumb not to even acknowledge someone you lived with for 8 yrs. Today i didn't notice her but she just walked by me without saying anything. she had to drive her car around mine as she was leaving and just stared right through me. Should I start doing the same or does it even matter.

Also I texted her S with some encouragement after the game again this is a kid I brought to all his sports games for 8 yrs. Is this bad or something she or you guys would interpret as pursuing
