Chrome, your future is far from hopeless. As a matter of fact you have three tiny little bundles of hope anxiously waiting for your return. You have seen the attraction from other women. Even if for some reason you choose not to work it out with W you KNOW you will not end up alone. My sister said something to me when I started having trouble with the W. She said, "You know, you are a much better catch at 42 then you ever were at 22". She is right. I'm sure the same is true of you. Your growth as "Chrome" shows a wonderful person who can be full of confidence (well earned, it seems to me), is attractive, sensitive, and all that other stuff that women seem to go for (hey the horse analogy ain't gonna work against you either ).
So, time to look for the good things. Stop listening to depressing music. Start listening to Madness or something equally inane and fun. You have 3 wonderful little children who need a strong father to look up to. You have a wife who loves you even if she is speaking a far different language than you at the moment. You have the respect of your peers in a highly intellectually challenging field. You CAN change your outlook and all it takes is for you to make up your mind to do it.
Gone the carvings and those who left their mark. Gone the kings and queens, now only the rats hold sway.
