Tricky situation

I am at the point in my life where I want family and marriage. I have a degree and I am working towards becoming an art teacher. I work 6 days a week and have a rich life with friends and family. I have a townhouse which I maintain and work hard to live in. I have paid for all this myself since I've had to work since 15, moved on my own at 17. Nothing has been handed to me.
Nothing has been handed to him but our work ethics are very different. I work 40+ hours a week (as a server while I go to school- I go to school on top of this), and he works 12 hours a week.
He is on disability for depression/anxiety. He is 30 years old and has been on disability for 10 years. He has worked the same types of jobs for 10 years. He was made no real efforts as far as I can tell to pursue more in his life. I have GAD (generalized anxiety disorder) myself and battled years with medications and doctors visits. I know how crippling it can be.

so what's your question?

I think it's important for two people to have a similar work ethic, otherwise frustration sets in. I couldn't be with someone unmotivated, who felt working 12 hours a week was sufficient. I worked full time whilst completing my Masters degree and some of this was while going through a bout of anxiety/depression-extremely difficult but I got through it. I never looked for a 'rich' partner because I support myself and the concept is gross to me - but I did look for someone who could bring what I bring to the table - I also know I can rely on him when I need to take time off to have a child etc.

It's been 10 years, the reality is he may never change. Can you accept this?
