Always talking about divorce...

My husband and I have been together for 5 years and married for 3 years. Weve have been fighting nonstop our entire relationship. We met 5 years ago while we were both in school, at the time we lived in 2 different countries and when we decided to get married. He made the move to me and decided to start graduate school. Things have been rough, and his school has dragged from 2 years to 3 years and now going into 3.5 yrs. Some factors that delayed the graduation involved his professor not being responsible for the project and holding him back. Now the project/experiment is done and all he has to do is write the Project Thesis paper but he has been dragging it with less than a month to finish. He has not begun any writing. We fight about all sorts of random things but mostly about school, money, jobs..etc. I am currently pregnant and we are expecting our first baby to be born early next year but my husband hasnt quite gotten his act together and we are financially unstable right now. And when we fight divorce always comes up.
