am i in love with my bestfriend?

first off we regularly say “i love you” to each other and know a lot of deep and personal things about each other like most of all our traumas and also made a death pact and are planning on running away together when we’re older and sometimes i can even see myself with them for the rest of my life but i can’t tell if it’s romantic love or a just a deep platonic love because i don’t get butterflies in my stomach or like regular signs of romantic attraction
if y’all have any questions or things to add please share
