It's kind of like you both have jobs that start at different times. He gets to commute while you stay at home and he probably takes a lunch and gets to interact with adults but still needs some down time to unwind from work but may not get it. You have to consider your son's nap, your "lunch"/down time. If you need to rest for an hour, take it or I would suggest going to bed an hour earlier since your "job" starts at a different time than your husband's.
Another idea is to adjust your son's bed time and try and get him to sleep until 7:30 and have everyone get up and spend some family time together and have breakfast. You can also ask your husband to pitch in with the house work. Your son is old enough to "help" with some things also. It takes longer with a helper but it teaches them a lot. My husband and I take turns cooking dinner and if I cook or we have left overs, he cleans up. We both also pick up a little once our daughter goes to bed so that toys are put away or the floor gets swept then or we fold a load of clothes while we watch tv.
I think if you get to sleep in on the weekends, that is great. I get this luxury when I am not working or at rehearsal. I also ask my husband to watch my daughter a couple nights a week when I am doing things for me or he takes her outside to play while I finish getting dinner together or if I need a break to get some work done.(especially if she didn't nap)
Another suggestion would be at 2, he is old enough for a mother's morning out program. "School" really helps them socialize and learn and he will love it and you will love have a few hours to yourself a couple days a week.
There is nothing wrong with asking your husband to get up early sometimes. It is my opinion however, that you both have separate jobs with different start times and you will have to plan your sleep and down times accordingly. Try and create a routine that includes help from your husband and think of things you can ask him to do that can give you a little more time if you need it. For instance it is perfectly ok for you to share the responsibility of the dishes and laundry. It is also perfectly ok to let the house work go a little to take a rest.
