My fiance and I just celebrated 6 years last month, but things are getting hard for me. At first I was supporting him so he could spend time studying his online courses. I work 40 hrs a week and am working toward a promotion at my job. However he doesn't do exactly what I expected...

I come home and he spends maybe 3 hours a week taking care of his courses, he sleeps in until 2 pm, does housework maybe once a month and doesn't feed our pets. What's even worse is that he's gotten involved in stocks and continuously asks for money insisting that he'll bring more in. I asked him if he'll start working when his summer semester is over since he hasn't applied for the next semester.... but he said he'll make plenty from stocks though those chances are dim... how should I talk to him about this? I'm working and working and of all things I don't want money to tear us apart
