Has anyone on here ever seen a sitch like mine actually work out or is this just a futile effort and something that I need to go through to get past her???

Last night I was in the plaza where my daughter takes dance and I happened to see my X drive through the lot to across the street where this guys daughter takes dance...this was 20 minutes before my daughter gets out...I saw her park on the side of the place and run around towards where his car was; but then I never saw her again; but I did see him and his kids come out of the building and leave??? I know I am obsessing; but I am afraid to get hurt.

I guess I am supposed to give her time to work this through right???
