Fiance trouble

I'm a full time college student, employee, pregnant and caring for my 3 year old. I get up at 6AM, get me and my son ready to go to daycare and classes, I sit at the college for 2 hours to do homework after classes, go home and have 2 hours before I have to work. Also packing to move and planning a wedding. My fiance? Staying up until 4AM playing video games and sleeping in until 3PM. And going bowling with friends on our days off. He is a great man and wonderful father, and a loving fiance. But I just want him to understand what I'm tackling here and I need support!! I'm so depressed and emotional and exhausted.
