zest for life

So first of all I have to say I love my husband more than anything.  He is the greatest thing that ever happened to me.  He is smart, funny, down to earth, and a wonderful father and husband.  That being said I am having a really difficult time with the fact he is not motivated to work or do something better with his life.  He has a wonderful opportunity to eventually become a full time Longshoreman (which in turn would allow me to be a stay at home mom) but he is not persuing this wonderful gift!  All he needs to do is work 1-2 days a week but he isn't making the effort.  We have had many conversations about why but nothing seems to help.  At this point I am so frustrated that whenever someone brings it up I just shut down.  I wish he had more confidence in himself that he CAN do it.  I don't know how else to help him. I am just tired of the financial pressure being all on my shoulders.  It is a lot of pressure and I feel myself crumbling and wish he could see that. I don't know how to approach the situation without him shutting down and without him saying that I am "nagging".  I just want what is best for Bailey.  If he was to work 1-2 days a week not only would he become full time at some point, but we would qualify for a home loan which is my ultimate goal!  How do I make him see my point of view?
