I'm extremely heartbroken, didn't realise how attached i got to this guy?

i went out with this guy for 6 months. i wasn't that into him at the start, but he completely made me fall for him. he cooked me romantic dinners, told me how special i was, played his guitar for me, gave me mages. I'm 19, he's 21. He never pressurisd me for . he made me feel so wanted. he wanted to see me everyday. told me how much i meant to him everyday. then i went to uni so only saw him once a week. things were just as good. he told me he loved me. this was only about 3 months in, and i was a bit weary. i wasn't even sure i wanted a boyfriend. but then i let myself really fall for him. i got completely besotted. depended on him so much. i was lonely at uni so needed reurance from him, and i was insecure. he is very ual and though. and though he isn't pressurising, he still get disapointed when i won't do everything wants to do. then if we don't get up to ual stuff, he just falls asleep. he never took me out properly. he doesn't drink, apparently doesn't like the cinema, and doesn't have a lot of money to treat me anymore. so it's just to his house to 'cuddle.' code for ual things. no romantic gestures anymore. his texts are very sparingly, and he only saw me twice since new years eve. i know he's busy. but could he have not found more time for someone he loves? when i asked him to meet up, he would be sick, or tired, or it would be too late. so i gave up asking him to do stuff. he was often late or stood me up (cancelling after the time) so i'd be dressed up and groomed. only to end up disappointed. it was embarring. i told him how this made me feel. he said "i'm never good enough for you." he then says stuff too, like he wants me to be his wife some day, and that he's so glad he's met me. but i feel like he barely knows me. i was having doubts all week. then he texted me, and without any affection first he just went straight into about . i got annoyed. and told him i feel like i'm being used. he said sorry. and i just wanted out all of a sudden. instead of waiting around for him to ask me to do something. so i broke up with him. i felt relieved. Now i'm sobbing myheart out. i keep thinking about the nice loving side to him, and how he truly cares, and i'll never find someone like him. he is being cold in his texts, but he says he is sorry that he mistreated me. and that he is hurting. and i said i was too. and he just went, "you'll get over it." help. feel so lonely, have i made a mistake, should i get back with him?
