My Ex wants to test feelings….. Good idea or bad?

My ex fiancé says she wants us both to go on a date with other people to see if our feelings are still as strong as they were before we broke up to see if there is a chance of getting back together. I know my feelings won’t change for her until I know there is not a chance for me anymore. Is this a good idea or a bad one? Is this her way of telling me that we are truly done? Or does it mean she still has feelings for me but is scared to get back together and just wants to test the waters to be sure? I would love any and all input
