my ex boyfriend and i are on a lease for a condo that we both rented together. we also traded in both my car and his truck for the car we now own that I am petty much driving myself and children in- which i have been paying for solo since he left. along with the insurance. we HAD a joint bank account which he no loner contributes to. Hes gone 3 months now.He is still legally married and I was under the promise that he was getting a divorce-- never happened . DO i have to return the car legally???
