This is probably the wrong question to say this in, but I absolutely hate the saying "fell in love" or "fell out of love." You don't fall in love or fall out of love. Love is a decision that is made. You either choose to love someone or you choose not to love someone.
Now that that has been said, I'm unsure how anyone here can possibly help your situation. You deserve better. Get a divorce and move on. I saw a news story last night about how a couple that is divorced gets together once a year and takes a family picture together just for the sake of their son. They're able to put aside whatever ill will they have against each other for a few minutes out of the love they have for their son. That's special.
