I just have to get this off my chest!

Even though I am married and I'm very blessed that I haven't had to go back to work yet and my son is 10 weeks old I can't help but feel like I'm doing this all alone. All and I mean ALL of the responsibility is on me. Yes my husband works a 8-4 job. He comes home and sits on his ass all night. He might talk to our son here and there but only holds him for a few minutes and then lays him down and let's him fuss. If he's just watching tv why can't our son sit on his lap? I do all the feedings (he's formula fed), all the diaper changes, wash all the bottles, makes the bottles, changes his clothes, gives him a bath, puts him to bed, stays up with him until he goes to sleep, gets up with him at night. If something concerns me he acts like it's no big deal. Tonight I felt like our son might have a fever so I take his rectal temp and left him on the couch right beside my husband so I could wash the thermometer off. All of a sudden my husband starts cussing and throws the wipes off the couch because apparently our son was poking himself in the eye with the edge and proceeds to yell at me saying I need to watch what he's doing. ARE YOU KIDDING ME?! He was right beside him! He can't watch him for maybe a minute so I can wash off a freaking thermometer?!? I'm just at my wits end. I understand that he works and he needs time to relax but does he ever think that I do to? I've told him before that it would nice if once a week he would come home and just say "hey babe I'll take care of Sawyer tonight. You go take a bath and relax." And I'm not saying he has to be up with him in the night and go to work the next morning. I just mean for the evening until bed time. Can he really not see that I'm frustrated and tired? Maybe I'm being selfish but I just wish he would do more. If he is fussy and it's been a while, make him a bottle. If he just ate, burp him and change his diaper. If you see empty bottles by the sink, wash them.  Why is this so hard to understand?!? I'm not complaining about taking care of my son because he truly is a blessing. It would just be nice to have some support and help every once in a while...
