WHAT SHOULD I DO? SHOULD I LISTEN OR FIGHT BACK?

OK, so, i've had this friend and he and i have been friends for YEARS! And this year we've hung out at lunch EVERY single day almost. Well, we sort of developed "feelings" for eachother, But he doest accept my family or my beliefs and hes not ready for a girlfriend. So we've just been hanging out and doing what friends do but then we took a break for a month and..... i sort of met someone else.... I really fell hard for this other guy because he likes me for who i am and accepts ALL of me. When this new guy asked me out, i said yes. So now he's my boyfriend. We've been going out for almost a month. But just the other day, he told me something that broke my heart in two. He said that he didn't want me talking to, or hanging out with my best friend anymore. I suppose he might be jealous or scared that i'll leave him for my friend. Or maybe hes worried because he knows that my friend has a part of my heart that he will never touch. But either way, It made me feel bad that he was telling me what to do, and that he didn't trust me to be with someone that i already chose him over. WHAT SHOULD I DO?!?!? Should i be humble and submissive? or should i fight for the right to keep my friend?
