I could be way off here, but his actions/statements remind me of my Ex-fiancee of 6 years.
It seems sort of odd, that he stuck it out with you thus far and now, when you can see the light at the end of the tunnel, he suddenly wants out.
Him suddenly wanting you gone makes me wonder if there's somebody else. He needs you gone, so he may cater to the new relationship and needs that to happen ASAP.
The fact he doesn't seem to care about your education & subsequent nursing career makes one wonder how strong the relationship is/was; It seems he wasn't the best significant other (putting it nicely) & eventually, the relationship will fizzle out. Better to know now than later.
Out of curiosity, whose name is on the lease/deed for house
Best wishes & Sorry for all this drama happening at a hectic time.
