I like this guy and I think he likes me... but I'm not sure.... what do I do?

My boyfriend and I, well, have a history. He liked my 2 besties and I liked him, and we started texting and then he liked all 3 of us. and then he CLAIMED to stop liking the other 2; and so I said yes when he asked me to be his GF, but it seems like he still likes my other bestie
