Bangs head on the wall

I've been in love more than once. I've had my heart broken more than I'd care to remember. I know how it feels to desperately want things back to where they felt good to me. I cannot, for the life of me, understand why Fernando will not move on. While we were married he spoke incessantly about how he could not wait to be rid of me. Now that he is he will not leave me alone. What really gets to me is that he leads in with something about the kids and it always ends with me having to say it's never going to happen...ever! I have actually had to threaten to contact the sheriff's office about him harassing me. Even with that he just HAS to text back a few more times. I swear! I have been completely honest with him. I have broken it down the best I know how. I am at a loss. He's even tried to convince me by saying that he'll stay gone on the road all the time.We don't have to talk, we can just text each other even when in the same room. I can have his paycheck (psh! if he keeps one). Who would want that? That is not a relationship.  The ink is barely dry on our divorce papers, which I carry with me as they make me smile ;). Why would I even consider him? His famous words are: forget the past.Yeah, that is possible. Maybe if the kids and I hadn't been through all that we have because of him that would be possible. unfortunately that is not the case. Any advise to get rid of this craziness is welcomed!
