Are you talking about how your ex-wife treats you?
Because if you are, I doubt that she
hates you. It's more likely that she knows you are holding on to hope for reconciliation, and doesn't want to encourage you.
It would be CRUEL on her part to allow you to believe that she would reconcile, if in her heart she knows she won't. If that's the case...sometimes it's kinder to slap a hand than to hold it.
