quite similar to our experience. My husband gave up his PhD for a job to support my MBA. I got the half tuition waiver. He is also a academic guy. So don't worry. After your graduation and secure a job, he can go back to school with your support to the family. Since you are already in U.S. and your husband is going to work, I don't think you need any loan. tuition is paid semester/trimester by semester/trimester, which means that your can just provide your husband's payroll and prove that you guys are making money. Good luck for everything.
Yes, I lived in Irvine for about six months and lived very close to UCI. Any question to the city, you may send me short message. Best wishes to your study.
