terrible headache, husband refusing to wake up and help me😩

Husband and I have been together 6 years and married for almost 3. We have two kids together who are both under 2. He had a cold all last week from Monday to Friday and I helped him however I could. He took a couple days off work (office job 7-5) to sleep and feel better. Yesterday his friend invited him to go dirt biking in the mountains for the day and all of a sudden he felt so much better and went. All the while I was on my own all day with no car (mine is in the shop) two kids under two and an awful headache. He left at 630am yesterday and didn't get back til 9pm so I did bath time and bed time for both kids on my own. He came home and I asked him if he could get up with the kids this morning so I could sleep since he didn't feel good, he said ok. Mind you he doesn't get up at night with our two month old, that's still left to me. So thus morning hit and our toddler woke up at 7. He got up. 710 hits and my toddler came into bed with me and was jumping on me all while I have an awful headache and had been up 7 times during the night with the baby. I go out to the living room to find my husband sleeping on the couch under a comforter and when he sees me he goes good you're up and turns over and goes back to sleep. Its currently 3pm. I asked if he was going to get up because I have to run errands and wanted him to watch the kids and he claims that he doesn't feel good again which I know is total crap because he felt fine when he wanted to go out with his friends all day yesterday. He's refusing to get up Nd has now moved back into the bedroom. I'm at a total loss on what to do. This happens more times a month than I'd like and I'm so frustrated. I feel like I'm parenting alone.
