You're in a tough situation and I feel for you.
If you decide to go with divorce there are ways to win 100% custody of your son. It takes a lot of work and planning before you file for divorce and you must take all the steps first and catch her off guard. If its the path you choose save some money, get a great fckin lawyer and an even better Private Eye to find dirt on her to make her seem unfit to mother a child in court. It'll be ugly but it works!
You gots to be nasty if you wanna win.
I truly do hope you work it out though
