As far as the 3 hour thing ... I would go nuts being a stay at home dad without a 'break' from the kids, 3 hours to me is not that much to ask for to get myself out ... do something remotely adult ... and clear my head. Now is he is MLC ... that head is 40x more cloudy than mine so I might not put pressure (We all know how an MLCr reacts to pressure) on this topic. If it were flipped, wouldn't you need some 'me' time?
As far as the EA/PA .... "Believe none of what they say and only 50% of what they do" right?
Your H knows that this is a deal breaker for you .. you were clear, why on earth tell you? Even more so .. the fact dude is a stay at home type ... where would he go?
Regardless of EA/PA or not, you DB or you don't .. the A (if its going on) is not the reason you are having issues at home, its all the stuff that has you here ... along with the MLC ... and the MLC typically has an A associated with it.
