What Do I do? My fiance has no motivation to get a job!?

Me and my fiance have been together for almost 2 years now and we have a son almost a year old. We both had the same job and about 2 months ago he quit and walked out. He was only getting 4 hours a week, but it seemed as though he didnt even try to talk to the management about it. Not to mention every one there at work didnt like him cause they thought he was a jerk. anyways Im the one bringin in a steady paycheck, but I only get 23 hours a week. So I dont even have enough for rent. The last couple of months have been very difficult for me. He drinks a little more than i would like and plays video games alot. I also used to drink alot, but now i dont like to waste money on beer. He hasnt seemed to really have any motivation or drive to go out and get a job. Its like he is content with barely just makin it. Well Yesterday our cell phones got shut off cause I couldnt pay them. I told him when i got home from work and he goes "i know." At that point I kinda lost it. he didnt seem to care. He keeps making excuses. for example: He always says "Its ok Im gonna go donate plasma and get $25." He does that twice a week and I could do it too but I hate needles. another example: he says "Im gonna have 3 or 4 baseball games to umpire this week. $35 each. Thats great but then i asked him about the temp agency and he said that hes gonna wait a couple more months when baseball season ends. Dont get me wrong those little contributions help but its just not cuttin it. He is a very loving man and a loving daddy, but i feel all alone when it comes to the bills, my feelings, and even him going to church with me. I dont know what to do. I dont want to leave but I am losing respect for him and I feel like im losing respect for myself...
