Should I marry him?(kind of long)?

I have a friend who is gay and in the military. Hes going to Korea at the end of the year and would like me to go w/ him. I'm going to school now so I can be an ESL teacher and I wanted to start in Korea(I am a few yrs away from the degree).The only way I can go is if were married.He considers me a good friend and wants to take care of me.He says it would really upset him if he found out I was in trouble and being so far away wouldn't be able to help me. The extra $ we would get for bills and things would go to me so I can pay for school and what I want.(It wont go to bills b/c living on base is free everything)A HUGH part of me wants to tell him yes but Im so afraid of getting Fu-ked over.He ures me that he won't but I can't help but worry.So random strangers if you can help me out w/o being rude I will gladly read what you have to say.(Also there are other factors that me and him have already discussed but this question was getting long)THANK YOU
