"I am in love (I think clouded judgement perhaps) but he has bought a house where I do not want to live"

I think unfortunately then your relationship is probably over. I am not in anyway trying to seem mean or condescending, but you have almost completely decided that you have no interest in living there.

I have always valued career as being more important than personal stuff, I would say be really careful taking the plunge and diving into a new career because your income is very important. It doesn't sound like you are happy though.

I hope things turn around for you, or that the direction you find yourself headed in is the right one.
