Selfish husband. No idea what to do anymore. Talking doesn't work.

Ok so my husband just got back from his second three day camping trip this month. He went with friends from work. He left me alone this weekend with our two toddlers who are 2 and 1 and I'm currently recovering from a recent miscarriage. Our oldest is sick so I didn't get much sleep last night. It's 4pm and as soon as my husband walked through the door he commented that our bedroom was messy, (there's laundry on the floor that I didn't get around to doing today because my son is sick) and then says he's going to bed because he's exhausted from being up partying the last two nights with his friends. He didn't even ask me if I would like to lie down knowing that I dealt with both kids alone for he weekend because we live far away from family and friends. He also said he's probably going to be in bed for the rest of the night because he's so tired so I'll have to do bedtime etc alone tonight. He spent zero time with the kids or me even though my babies were crying for him, he just shut the door behind him. He initially wanted to lie on the couch and sleep but he was snoring so loud I told him to move because it was making me tired and I've barely slept in 48 hours. What do I do here? I feel like he's taking me for granted.
