Well, that is kind of the truth bottom line but it's not the whole truth. The truth is Mom and Dad are not a "couple" anymore so things will have to change.
As the Mom, you get to be in charge, that's the good news! I frankly don't know how you put up with this visitation and him being there for hours. I'm pretty open minded and patient when I have to be but this would be beyond my patience.
How about supervised visitation. Can you meet at a park, the zoo, ice cream place, somewhere where you could have a cup of coffee and surf the net or whatever and they could have a short visit.
I'm guessing while he is busy channel surfing there isn't a lot of child/father deep conversation going on.
How he can be so offensive as to start talking about holidays in Spain while the kids need new shoes and he has you paying for the boiler?
You need a lawyer.
