My marriage is in a limbo, we have had many prolems in the past 6 years my struggling to have children, finish

ing college and now he wants to go to a university that is an hour away and live in an apartment while I work and pay the bills. I know he has sacrificed for us by working crappy jobs and even supporting me for six months while I went to school to complete my bachelor's degree. I went to a campus locally, and it just does not sit well with me that I will only see my husband on the weekends. He says I am very negative person, which I can be but who wants their husband to be away from them like that, am I being selfish? He says this is a chance of a lifetime opportunity he will be working part time at his college and going to school full time while working on his master's degree. I suppoert him going back to school but I am uncomfortable with him living on campus. Help me
