Dar there could be any number of reasons why he hasn't filed they often don't if you read the threads. Often its the LBS that just gets so fed up living in limbo land or siting at the end of their peice of string waiting to be jerked.
Often we file as in my case (rem I am alot older) purely for financial reasons and to get some control back of our lives.
They take the line of least resistance, as long as he doesnt see the need for a D he probably won't. He's got his own life anyway. Thats what you need to do. GET your own life. I always caution people about finances though-having been burnt so to speak. Look after yourself on that one. These men can hide and spend like money is going out of fashion. Remember its actions not words. They can all spout what they think we want to hear, is it the truth?-well truth is backed up by actions. I call it manipulation. Don't even worry or think WHY he hasn't D you. Thats giving him power over you and your thoughts. Are those eyes dry yet?
