Bf problems

Hey ladies I have a question does ur man make u pay his gas sometimes when he’s running low and sometimes u guys don’t even hangout for the amount of gas he has used? We both are young he’s older than me and I work and go to school I pay rent for my house hold i help my mom out he’s 17 I’m 15 (chill it’s a 2 year difference) Everyone makes a big fuss about the age difference anyways I’m just concerned how I have to pay gas for him and everything for the time we don’t even hangout on like we barley spend time and we barley go anywhere far he just parks somewhere close and sitS there
