I have been living with my bf for almost 3 years we call each other husband and wife and so do a lot of people. I want to leave him due to his cheating I have proof of that. He leased a car out for me because I couldn't and have pictures and texts saying it's my car. Would I be able to take the car with me since it was a gift? Do I have any other rights to anything else? We did not file taxes together because I don't have a SS Number and I didn't know if it would affect in a negative way. I have people who are willing to write letters stating we have been living together and that we call each other husband and wife I have pictures of us wearing rings and pictures of our cell phones saying husband and wife under contacts.
