So many problems in my marriage, I don't know where to begin?

Well sounds like he has to quit settling for this mediocre paying job and find something that pays more..... so he needs to quit being so pissed about it and do something.... people who wallow in self pity and kick their families around are cowards..... you say hes a good man yet when hes home he wants his own time and snaps at you when you want a little attention..... so.... why are you sticking up for him? He needs to own up and change his life rather than take it out on you... you have your hands full with your son.... your right, you cant work right now..... and thats understandable..... sorry but your husband has to make the change for the better..... all you can do is continue what your doing because I dont see anything wrong with what you are doing.... good luck
