Unsure of the future with my current fiance.

So I'm not sure if I can or should continue my relationship with my fiance or try to fix things. We've been together for two years now. When we first started dating they said that they were working on finishing their masters degree but they have not done so. They also said they'd be going back to work after they finished their degree. They have just been running through their savings and staying at home. They do most of the chores but the house is often a bit of a mess. Now they're saying that they want to wait until after kids to go back to work. My family also thinks it is a bad idea to marry them.
