Merry F'in Christmas - I want a divorce.

Yeah, don't tell your son that its the end of the world. When I was growing up I had the Momster and then, I had an actual parent who was my Dad. Since my Dad was in the military, I would sometimes be left alone with the Momster for long periods of time. My Dad would take his duty orders in stride (at least when I was around) and this helped. I still blamed the Momster, though, and not the Army for his periodic absences. I figured she wanted the extra cash his hardship pay brought in, and I was actually right. My Dad never said this to me, though. Even when we had to be apart he wrote me almost daily, and I clung to the life line he offered by being the one loving parent in my life. You can do the same for your boy. Fight like a tiger for at least joint custody. Use your anger in a constructive way to help you get past the pain. Anger channeled appropriately can help you fight for what's best for you and your son, rather than giving way to sorrow.

And yes, somewhere out there is a woman who is just going to be delighted to have both you and your son in her life and give you the love you both deserve. Mark my words.
