My husband is a pig and I'm a fool?

Me and my husband separated awhile back -- actually I threw him out of the house because I couldn't take living with a human-ape-pig any longer. We've been trying to work things out but I gave him a long list of thing he had to change before he could move back in. It seemed he really didn't care at all. So, yesterday, like clockwork, he comes home to his bug infested nasty trailer and his power has been turned off. This happens to him EVERY month. He called me all pitiful cause it was so hot last night and he couldn't watch TV so I gave in and let him come back. Of course he gets here and eats ALL the leftovers in the refrigerator, drinks 13 beers and then we have one-sided, sloppy until he rolls off, farts and pes out. When I came home from work this afternoon that idiot and his two idiot 'friends' (that I can't stand) were working on a truck transmission on my kitchen floor! There was oil all over the place, greasy hand prints on the floor, walls and toilet. There were at least 40 empty beer cans and bottles littered through out the house, cigarette s in the sink, old Burger King hamburger wrappers on the counter and sofa and tools in my kitchen sink. I didn't know wether to cry or load my shotgun and just rid society of ALL of them. Of course my 'husband', the head idiot in charge, is sitting on the floor wearing nothing but boxer shorts and covered in grease from head to toe asks me to 'go on a beer run' cause they're out. I never knew I could cuss like I did this afternoon. I was using words that only longshoremen and convicts use and I screamed so long and loud that they scooped up all the parts and tools and ran out the back door and left. Well my sorry man-ape with his B.O. and long ugly toenails and smelly breath and loud, wet burps and sonic-boom snoring and constant farting and smoking and drinking STILL hasn't come home tonight. He called about an hour ago and said they were still working on Rusty's transmission. I just got my house clean and I'm so tired I've been weeping for hours as I mop and scrub. What do I do? What would you do? Please!!
