Am I really in love?

is it possible to be in love at 14? I genuinely belive I love my boyfriend. we've both told eachother that we love one another. a lot of people think that teens arent emotionally mature enough to know what love is, but me and him have the most genuine bond. Hes truly my best friend and I can tell him anything, and I know thats its not lust. just say your opinions below!
