i was in a relationship with a gentleman for 19 months and in this time he paid no bills or bought nothing for my rented duplex i shared with my mom...a month ago i purchased a mini home and he moved into it with a lease agreement signed stating he was renting a room for $ per month he was only here for one month and again failed to pay a cent so i got him to leave ...now he is saying he is going for half of all i have since we have lived together for a period of time ..does he have any rights to my assets when he has not contributed anything
