cheap boyfriend

my boyfriend is really cheap and it’s starting to really piss me off. when i got my license i would drive him to school then to work after school and then on fridays i would pick him up from work and stay over at his house and drive him to work the next day. (he didn’t have his license at the time) and this went on for a few months. he gave me gas money like twice and it was maybe 5-10$ (i didn’t mind at the time because i was being nice and plus he’s my boyfriend) but as soon as he got his license he would always tell me i was driving and if he does drive me around (where we live there’s nothing to do so me and my friends just drive around listening to music for hours) it’ll be for maybe 10 minutes and then he’ll drive me back home saying he “doesn’t want to waste his gas” witch i understand but the amount of money and gas i wasted on him i feel like he should be driving me places. it makes me so mad and sometimes i feel like he was just using me for rides. anyway today he said he’d take me out for dinner once i’m off work. like 15 minutes before i got off he texted me saying i should pay for dinner so i said “no you told me you’d take me out” and so we ended up not going out. i don’t know what to do it frustrates me how cheap he is and my parents also agree that it’s unfair to me and that he’s my boyfriend he should be getting me things and driving him places. i buy him a lot of things all the time. i gave him 20$ for gas the other day because he told me i had to. and he smokes all my weed all the time on me. what should i do about this???
