Does my boyfriend love me?

how would i know if my boyfriend loves me? we have been together for two years and im his first boyfriend ever. he doesnt kiss me n public or hold my hand. when we watch movies and there romantic he would smile and stuff and huff and puff!! i dont like romantic things and he is upset with that. and we had a conversation about if we broke up he wouldn't care because there is nothing he would do bout it. or if i cheated he said there is nothing he can do about it. so i dont know what to do or how to react.
