damn, so the 'treaty' doesn't allow you to complain?? Like hell! If it says ONE thing, it needs to be ONE thing, if he doesn't like it TOUGH that was HIS terms. If the terms are worded differently or more ambiguously then that may be an issue. Make HIM be the one to demand it be redone. Then you both aren't 'violating' it, he is and he can sit on it and spin.

Sounds like the dad is just way in over his head with his wife and job, maybe the two of you need(well three, him and you two) to sit down and just talk. Make him understand. If he's already had a 'breakdown' in a previous conversation it won't come as a huge shock to him that you think this way, and since they seem to have one of you on a pedestal and the other in the scullery it's a good balance. If need be get in a third party like an aunt, grandparent or close family friend, someone who's not really involved in it that can help mediate.

The absolute end of it you can look into public assistance. Yeah, it sucks, but really, that's why those programs exist so you DON'T have to be 'stuck' in situations like this.
