Too proud

My husband and I have been married for ten years and there is a considerable age difference between us. We met at a gas station where we both worked. When we first got married, I was just coming out of a bad relationship and he had been a confirmed bachelor for several years. I had two kids with disabilities and I was so amazed that this guy was willing to commit to me considering all of my baggage! I started going to school a few months after we got married and when my husband saw how much I enjoyed being in school, he started going to school too. Now my husband has a master's degree in software engineering, but we live in an area where his degree isn't useful. He also has a criminal record with some time spent in the penitentiary. Once my husband completed his bachelor's degree, he tried to get a better job, but when nobody would hire him for a better job, he just quit his job altogether and has relied on me to support him for the past three years. I love my husband dearly, but I am very close to giving up on him because I can't spend the rest of my life like this. I'm currently working two jobs and I am still going to school for my masters degree. I have had to give up most of the things I love about being a parent because I don't have the time or energy to do them. I have watched my health go down very quickly and even with the large gap between our ages, I feel like I am in worse shape than he is. I feel like I am killing myself for nothing and in wasting the happiness that comes with youth in the meantime. I am incredibly frustrated.
