College degree's & our future

My fiance popped the question on new years eve and we decided to put off the wedding until we were both done with school and able to support ourselves. It really sounded like the perfect plan! But, some unexpected events happened and I moved home and went to a school closer to home and he did the same. I live in pittsburgh and hes 5 hours away in Cincinnati… Ill be graduating in 2 years and getting a teaching job. He would be doing the same but hopefully getting a job in marketing/advertising. Well, recently, he got hired in a sales position at a gym and has the opportunity to make very good money after a couple of years. at the end of this year, he coupld make like 70k.. and if he stayed for a couple of years, he would make well into 6 figures.. They sent him to cali for an intense training program and everything was paid for. From what I hear, its a great company to work for. The funny thing is, of the 3 people hired, hes the only one “still in school”. The other 3 have a college degree and tons of work experience in sales. Im SO proud of what he has accomplished.. I really am! But, he now just wants to do that job and just forget about school. He gets really angry when I bring it up and tells me he has some debts from the online school he tried that he has to pay back before he can go to school. Our original situation was him staying in cinci for the semester and then coming to school with me at point park university. Obviously thats changed but not being able to see him has really been hard on me. The thing that hurts/scares me most is that he might not finish school.. I try to tell him that he might not be so lucky on the next job he has and he will need that degree. He seems to thing everything will be fine. I knoew the lifestyle we both want and not having a degree would realistically not let us have that. It sounds selfish, but I need to look out for us and out future as a family.. I just dont know what to do. Hes my heart and soul and I love him more than words can describe, but I dont want to be having financial difficulties down the road because he didnt finish school.
