When we moved to a new state my son's friend missed him
Why did you move to a new state?
I divorced my wife, and I wanted to get away.
It's understandable that you wanted to get away from your wife, but making your son have to find new friends just for that reason is bad. He will have less stability. You should move back and learn to deal with your ex-wife.
I didn't think that would happen. If my son ends up being bitter about it I blame my ex-wife
Your kid finding new friends will have a difficult time, or maybe he won't. But moving away from his mother would be devastating enough for him. Please move back and just stay away from her.
