If it was hurting me in some form, I'd probably leave initially but try to get the spirit exorcised or whatever so I could return.  Hubby is very superstitious and freaked out about death and dead people so I'm not sure if he'd ever return.  My house was built by and lived in by my great-grandparents before I inherited it and I'd tease him about them being around (even though I had no paranormal indication to that effect) and he was weirded out by that with no proof.
