how do i know if hes worth all the trouble?

my bf and i have been together on and off for almost a year now. we've had constant fight because we cant find time for each other as i have studies and he has work. a month ago i thought we had broken up for good and wont be getting back together but then he had an accident and the feelings started to come up again on both sides. m not sure if i should move on or give it another try.
