husband sleeps 18 hours a day

We have three kids all of them were planned (the last one was his idea) and have been together 6 years. Last night he came home at 1am, drunk, without his car (thankfully) after hanging out with friends. He went over there at 5pm and told me he wouldn't be long because he was just helping his friend fix something really quick. No text or call back until he rolls home at 1 with no excuse and apparently they didn't even get what they needed to get fixed finished so he's going back over today and possibly tomorrow on effing Father's Day?? It's now the middle of the day and he's still asleep. Our two year old was up most of the night last night because he was sick so I'm literally running on two hours of sleep and he knows this. On some weekends I've literally seen him sleep for 18 hours a day (providing his friends don't ask him to hang out) and he thinks there's nothing wrong with this because he works an office job 7 hours a day during the week and I get to stay home all day😑😑 We've taken him to the doctor and had every single level we could possibly think of checked and they all came back normal. I also do not think he's depressed I think he's just lazy. I'm so mad because he's sleeping the day away but then will have all the energy in the world for his friends tonight. Or would have energy if he was going to get sex or a blow job. Why can't he just wake up and spend time with his kids on Father's Day weekend instead of sleeping his life away? This is the biggest problem in our marriage. He's never once gotten up with the kids during the night or in the morning. He even slept the whole time I was in labor with our last child because it was in the middle of the night and "just because I was in agony doesn't mean he didn't need to sleep". He woke up for 10 minutes while I pushed our daughter out and then complained he was going back to sleep because he didn't get a restful nights sleep because I was making so much noise DURING MY 19 HOUR NATUARAL CHILDBIRTH.I barely slept while in the hospital because he was constantly sleeping.  I'm still getting past that. I had to labor all on my own and he completely ruined my birth experience with his incessant need for sleep. He still thinks there's nothing wrong with what he did and says I'm overly dramatic and most women do it alone😒
Right now  I can hear his snoring coming from our bedroom and it's annoying me so much because he's been sleeping 13 hours and I'm running on two. Our kids keep asking if he's ever going to get up or if he's just going to go to his friends house right when he wakes up again? As far as I know we have a happy loving marriage other than this. I just don't know what his problem is. Whenever I talk to him about it he says he needs sleeps and that's if. I feel like crying and don't know what to do😔
