Oh yes, we would go months/years without contact - and when he did contact me it was often abusive. When I saw him in February of this year I hadn't seen him to speak to since around June 2010 (although I did see him in court when our divorce was finalised).
He called once in September 2011 when my middle son was going through a bad time, and we have emailed once every few months since then. My bomb drop was October 2005, and he was a real touch an go merchant. Usually out of the blue suggestions for reconciliation, which I can now see were nothing of the kind!
This latest round is very strange. I am far beyond anger, and have nothing to prove. In fact, as I mentioned it is actually quite funny. I find him a bit dull and sad to be honest. Oh dear, not a very nice thing to say.
