If you are working and have an hour lunch, take a cat-nap. I sometimes break my lunch in half and take a 20 minute nap and set my phone, even if I'm just putting my head down on a table. I also have done that in my car in the parking lot (doors locked). I am always exhausted but usually can't get in to bed until 12:30 or 1:30 on a good morning and am up by 7:15 for work, but I used to go to bed much later. (I'm 9 months pregnant with my 3rd, so I've been heading to bed earlier and leaving my husband up--I totally understand you wanting to spend more time with your husband because I fall asleep sitting on the couch with mine and it has always been a struggle for me to stay awake. He works evenings and has had insomnia most of his life, so he is almost always up much later than I am.)
Another idea would be to work out right after work--it might give you a second wind to keep you awake. Drink lots of water, but not right before bed--water wakes me up more than coffee in the evening sometimes. Play a game with your husband instead of sitting around, which makes it easier to fall asleep. Board games or thinking games might work or something more fast-paced. If he is home, though, make sure you are still getting enough sleep. You mentioned when you get to bed, but not how many hours you sleep. I can sort-of function if I get at least five, but really do better with six, so when I'm only getting 4 or 5 I shut down completely.
