LOL. Yeah - During my first divorce (which he asked for), he never filed the papers. I was a broke student at the time, but I finally got off my @$$ and paid the $500 to get the papers drawn up. (Doesn't seem like a lot, but that was over 2 months rent for me!)

The look on his face when I showed up 'out of the blue' and said, "Sign here please." was priceless...

Some guys just are irresponsible losers. I think that even if they showed some responsibility during the marriage (most likely because you pushed them to), they swing in the complete opposite - and extreme direction afterwards. I wouldn't worry about him scheming. Even if he is, he still has to get his @$$ off the couch... and I doubt that will happen.
