Anyone have a husband that does nothing?

I have a husband that does nothing he does not work outside of the home and stays home with our child but does no housework maybe like once every 3 to 4 weeks. I barely make enough to keep our heads about water and he seems so lazy, depressed, unmotivated and has anger issues and says hes looking for a job but i am working full time and looking for part time work and have two interviews set up tomorrow so how can he not find a job when he is looking for them in the same place that I am online? He always gets angry when i come home after working 8.5 hour day and have to do the dishes clean up the house and take care of my 9 month old all night, feedings, bed, bath ect...it gets me so enraged at him that i get angry with my son i have no fuse left. I would NEVER hurt myself, son or husband (occasionally throw things not hard and not anyone or anything) I just can't stand it anymore... he contributes to 450 of our monthly bills but other than that everything is on my shoulders rent, food, his cable/internet which he couldn't live without due to his game addiction of xbox and watching movies all day and having some beer while i am out at work and i don't think i can take it anymore! I have no family or friends where we live and my family is accross the states i have money saved up but not enough to get myself and son and have a little one due in 3.5 months from now... i don't think i can do it on my income on my own but i want to so badly! I need some advice on what I should do and if anyone else has this problem i have been researching all over the internet and all i can find is woman complaining that there husbands work all day and come home and do nothing he doesn't work outside or inside the house and gets angry with me and belittles me and has really no respect for me and screams that he doesn't want to hear it when i get angry that i have to come home from work to more work every single day. and don't get me started on the weekends I have to be the full time baby diaper changer, bather, feedings ect i love my son and i love being with him when i get a chance to but i am really exhausted overworked and sad.
