To qasze: he refers to live together rather tahn getting married

Once you get married financially it will be more complicated. The way he suggested is not a good deal for you. First it is not what you want, secondly you will end up doing a lot chores and still feeling living under somebody else's roof. Don't lower yourself for little bit free rent, you worth a lot more than that, it will only make him go above you and if you move in with him, you'll lose your opputunities for better chance.
