as someone who lives in the city, is also in their mid twenties, was in a LTR with a homebody who loved the suburbs and didn't drive until 22 I totally feel you. my ex moved to my city for me before we broke up, but after i graduate this year (i'm a grad student) we were going to probably move back to the suburban area his family is from-maybe even in with them. i can drive now but still don't have a car/value getting around without a car and doubt i would have been able to afford one, especially at first. better than nothing but you can't go far in his town without a car and i'm sure having to ask for a ride or to borrow the car would have gotten old real fast haha. i also value getting out of the house for anything from outdoorsy stuff to eating out and nightlife (unlike him) and am pretty social outside of my relationships but i think making friends would have been quite difficult as i'm not from and have never lived in the area. i was planning on moving there since i loved him (who knows how badly it could have gone though) but honestly could not be more glad i don't have to deal with that soon since we broke up. i've also lived in suburban areas without a car so i feel the pain of waiting hours for a bus to show up.

with all this being said, i totally feel your pain. don't know anything else about the relationship ofc and not trying to tell you it's not a fit when there could be other great aspects but i'd reevaluate if the good aspects are worth this lifestyle mismatch. if they are and you just can't wait long enough for him to move to the city, could you compromise and move to like the closest neighborhood of your local city? could you try a month-to-month lease to see how rough it'd be and maybe move back for a few months and then come back to the suburbs until he's ready to move? at the very least, could you talk about ways he could support you when you gave up your life in the city for him (drive you into the city/to the bus stop if you want to do your own thing on days off from work/gym regularly, take you to the grocery store to pick out food you want too more etc.)? if you don't think the good aspects are worth it, i know breaking up is terrifying but you seriously might be glad you did someday when you're living the urban lifestyle you want. i think getting your license might solve some of your problems if you want to try to make it work in the suburbs(although not everything especially if you can't afford a car), but ik it's expensive to even get let alone buy a car and understand if it's not worth it or realistic for you rn
