Dilemma

I need to complain again. Sometimes I feel like all I do is complain. I guess this is a good place to do it. So, my husband and I bought an elliptical for Christmas. I used it for 3 days in a row and enjoyed it. Here's the dilemma: my husband was on a break from work making it a bit easier to let me use the elliptical while he watched Asa. He started work again on Monday and it has been two days since I have been on the elliptical. I'm thinking exercise will only be a weekend thing which sucks. I NEED to workout! My husband is on his last class for getting his bachelor's degree and he has two big papers left. He got an extension (he was suppose to be done Dec. 20) because of his mother's passing. I am hoping that once he is done with these papers there will be time for me to workout when he gets home from work. It's hard because he gets home from work at around 5:00 and if I were to workout it would be 6:00 by the time I got done and showered. We need to make dinner and eat too. I've thought about getting up early before Asa wakes up but I'm preferring sleep these days. I thought about exercising during a nap time but the time he naps isn't consistent. I'd like to workout for at least 30 min. and then shower but sometimes he only sleeps for 30 min. I've also thought about exercising when he goes to bed but I go to be an hour after he does and I'm way to exhausted by 7:00 to think of exercising. Any ideas of when I can exercise? I'm also so anxious for the spring to get here because then Asa and I can go for walks.
