My husband wants to move for grad school but we can't afford it?

My husband got accepted for grad school in Hawaii and wants us to move to there. We had planned that if he got accepted he would receive tuition istance and a stipend so there wouldn't be as much of a financial concern. However, Hawaii is not going to give him tuition istance and we will have to pay non-resident tuition for the 2 years that he will be there for his masters degree, possibly a lot more if they accept him into the PhD program. I want him to follow his dreams and I feel that he would regret it if he doesn't go. He refuses to apply to grad school again so he thinks that he has a go now or he will never go . Money is one of my biggest concerns because Hawaii is expensive, I don't have a degree, and I am not a local so it will be difficult to find a job. I have done some preliminary cost of moving calculations and we would need a lot more money. I mentioned getting a part time job this summer but he refuses to think of doing that and I don't think it would be fair if I got one and he didn't. I also ran some calculations on the cost of living and we would be in a deficit - which he denies. He plans to work part time and go to school and I would work full time. I dont think I could get paid more than $15/hr. We have a pet, so that would mean we couldn't take advantage of cheaper student housing and would have to find an apartment on our own. I also really like the job I'm in now because it is giving me experience in higher education - a field I would like to have a career in. I feel lucky that I work for a college now without a degree and don't think I can get hired in Hawaii at a university without one. He seems to think my experience will be able to overcome the lack of degree. I also want to earn my degree which I can do online but it will mean more loans on top of the one's he already has the the one's he will get in grad school. Since we had to give the university in Hawaii a decision last week we decided to tell them yes, even though I wasn't sure. I told him that I might change my mind. Since then he has become more and more confident that we can make it work and he is as happy now than I have ever seen him which makes it difficult to talk about my worries. I have mentioned the idea of him going without me for a semester or possibly the whole 2 years but he refuses to go without me. Any advice, suggestions or ideas would be appreciated. Thank you.
