I don't know what to think!?

im in a long distant relationship right now w/ this guy i am absoulutley in love w/. i dunno if he loves me though. he tells me he does and that he means it, but i don't know if i should belive him. i'v had guys tell me that before and it wasn't true. and last night he told me he met this really cool chick. he said that he really loves me, and if i lived closer then we would be in a real serious relationship. but he wanted to know if i would get mad or jealous and etc. i told him no then and hung up and cried for 2 hrs strt, then called him back spilling out my heart and telling him i do and don't want him to go out w/ this chick. i told him i don't becuase im in love w/ him but i do b/c it would be better for you ad that she's probley better than me. he then yelled aat me telling me to never say that again that no one is better than me and that he loves me and stuff. he said he LIKES this chick but he LOVES me. i dunno what to think. does he love me. should i waste my time on him?
