Gonna throw my 2 cents out on this. IMHO it sounds as though H is spread abit thin. His job, cattle business, farm work, helping parents, work on M, etc. When one has this much going on it is easy to blame it on the weakest link for the level of stress i.e. the M. Seems to me H uses this as the thing he can lash out on and lay it all on. Most sons will not blame their parents cause we feel it is 'our' responsibility to help out our parents and not tell them no I am guilty of it to be honest and it was a sore spot in my M. Now I'm not going to blame my job for the stress cause it pays the bills. I'm not gonna lay it on the business I/we are starting cause it will be the future. So I know the one thing I can take advantage of the weakest link so by the time I get home I just can't be comfy cause you want something I just don't have it.
IMO it's the old adage you hurt the ones you love i.e YOU! Not that he is doing it so much on purpose, but maybe cause he feels if he disappoints you it's no lose cause he already feels like he has in the past and isn't putting himself into like he knows he should. I don't know if I am saying this right or how I wanted to kinda tough to put into words so foregive me if it doesn't make sense.
IMHO I would go back to acting as if, lay out your boundaries, ask for what you want as you said in your last post be the calm for now. Dig deep for more patience stay up with your running and working on you.
Again if this doesn't make sense I apologize, just seems to me he is using you and the M as the scapegoat for his stress cause he doesn't want to 'look bad' in front of others...
