S.O. has gotten so lazy

my man has gotten beyond lazy. all he does is sit on the couch when he isnt working. i work at home taking care of up to 6 kids. He's not even very mobile at work. i have serious back/neck problems and i still do everything that has to be done. he cant even throw his trash away. he leaves it on the counter next to the trash can. im fed up. he does absolutely nothing to help me. hes never even given our 20 month old a bath or anything. he doesnt sleep in our bed. he sleeps on the couch cuz god forbid we disturb him cuz he has to work. hes never affectionate with me. i needed to rant. i go to bed pissed off every night. im to the point i cant stand him. if i wanted to be alone id be single.
