Tic tac toe

Against everyone's finger waving, I have decided to be friends with my ex girlfriend. I don't understand why this is such a bad idea. We experienced a great connection and just because it didn't work out in a full blown relationship, why can't it work in a friendship? That connection just doesn't go away-- unless your ex is an asshole and did something shitty to you. The "X" is an interesting concept. Before, was she an "O" like this was tic tac toe in the game of life? "Ex" is defined as without, without a value indicated value or right. To me, everyone's ex had some value at some time, but when you break up does it take away the value- the memories you shared, the things you experienced? Verdict is still out.
