I am in the same place as you. My husband works 2 jobs and goes to school full time, he never has time for me. It is really tough, I know, but just hang in there. He isn't doing it on purpose, I thought that for the longest time, and I got really upset at him because of him not spending time with me. Try to find a relaxing hobby that you can do, that makes it easier to get through the day, believe me. Best of luck, and try to not let it get to you too bad.
I know how you feel. My fiance works nights and sleeps during the day while I'm always home alone with my 6 month old and here I am pregnant again. Lol. It *****.
