Hey BBJ, isn't it ironic that both you and K are waiting for your husbands to act in order to move on. You both have been waiting so long and now your husbands are still making you wait....
I have always said that the divorce (for me) is just a piece of paper. You need to move on in your minds. If I did not go through this myself I would be incredulous that two women like you and K are still stuck some how. It is difficult...I know. As I told K today, I wonder what I would do if XW came back and pulled the right strings. After a while regardless of your religious beliefs, it does not make sense anymore.
So my suggestion to you both is to try to rebuild and try to turn the page. Talk to yourself like I do (and did) and maybe you may start believing what everybody knows, you guys deserve so much more.
As far as signing the receipt is concerned, he sent you an email..."reply" to it with the request above (ie. sign the receipt please). After all he put you through, you should not only put a mosquito in his ear but you should swat it with a heavy instrument.
