I would hope that you did contribute to the bills etc. No matter what your circumstances you would have been required to do this. Did you actually pay for the purchases of the houses and if so have you the proof that you did? If not then as your partner didn't die suddenly, I am surprised neither of you discussed what your standing would be as the prognosis of that type of cancer is not good. It seems you have no choice but to leave the home and find another place, this time making sure you know where you stand, lesson learned. Very sad but being a partner, unless wills are made accordingly, does not mean you are entitled to anything of his.
