@Kristenstraine,
It sounds like you need a lawyer - maybe. It sort of sounds like the mediator's big ideas got shot out of the water, but it is kind of hard to tell. If the action is not over, and that's the way the mediator thinks, you definately need a lawyer.
Anyway, you now have sole legal custody, and he has 8 weeks of supervised visitation. Is that right? What did the judge order after the eight weeks expire?
If you are going back to court, and a lifetime of visitations are on the line, I can only say again, you need to come up with a lawyer - especially if the next hearing might somehow call your sole custody into question. You could have serious problems if he comes up with his own lawyer, and you have none.
