Am i a bad person ? does he like me ? did i mess it all up ? do i leave ? but all the history we have ?

okay , im 21 and im best friends with like 4 guys who are in a band , i live with too of them who have there own house , they go on tour a lot and im left by myself a lot , anyway , one of them jack he has been my best best best friend forever and we the guys who to say he liked me , he would allways get a little jelous when i went on dates and he stoped talking to me for 3 months when i had a boyfriend , so i asked him stright up wht hes deal was , then he kissed me and told me he loved me , i had a boyfriend at the time who i loved so i told jack that it was too late , i siad we can still be best friends , so we started hanging out again and we where all good but about 3 weeks later my boyfriend cheated on me ( which jack had siad from the start but i never listened ) anyways we broke up and i started acting in a bad way , i was leaving the house for days without coming back or telling them where i went , i started getting drunk every day and started doing all sorts of bad stuff with guys i diidnt even no , anyways i got in some trouble and they guys had to safe me , they told me if i diidnt get strighted out that they would kick me out , so i got strightened out and things where normal again , after a while i got a new boyfriend and again jack kissed me and told me he loved me , its like he only wanted me when i had a boyfriend never when i diidnt , he diidnt talk to me for a week after that , i asked the guys wht his problem was and they siad that he only siad he loved me whn i had a boyfriend cuz he was scared tht if i diidnt have a boyfriend i would still say no and then that ment i diidnt like him , but if i had a bf and i siad no that there was a reason ( is that a guy thing ?? ) anyways , i broke up with my bf for jack and we started going out and everything was perfect , such like a movie , we dated for 6 months in this time they went on tour for a while but not long only a week here or there , one day i woke up and i got a text saying , i think we sould brake up , i dnt love you anymore , as i lived with jack and his band mate , it wasnt like i could just not see him anymore , he was allways there , i diidnt talk to him for 2 weeks after that and him and the guys where acting really werid around me and stuff , i had a really close guy who i stayed with a couple of nights just cuz i was over the weridness at the house , i diidnt understand why the guys where actiing werid around me too , not just jack , i found out that a guy i use to date told jack to brake up with me or he would send nude photos of me to everyone , when i went home i find jack and told him i no why he broke up with me , i told him i diidnt care about the photos only him , so we got back together , fast forward to 18 months later , every thing as great again but then his band got bigger and he went on tours for about 2 months at a time and i was left by myself , one day i got a phone call saying i had a job offer in new york for a fashion company and it was like my dream job i had been working for my whole life , we live about 7 hours away from new york by plane , so sould i stay with him or leave to go on my dream job , i dno why i siad all the history but thought it would help . things where finally great ? how can i leave ? sould i leave ? or stay
