It will do me a lot of good to distance myself for the weekend.
Physical distance is one thing. But really THINK about why you are doing the things youre doing. For example, if you go to her church on days without the kids. What is your true motivation? Between you and the mirror... If we really boil it down... Is it to see her? Is it to show her you care? Is it to show her you are a good dad? I dont know, Im just asking... You dont HAVE to talk to her when she approaches you at the game. Why do you?
In my opinion, it sounds like you are pursuing her, even if you dont mean to be.
