When are your I love yous on text genuine?

im a little narcissistic which my best friend knows so he always avoids admitting he loves me bc he knows it’ll only boost my vanity and he's always careful who he says i love you to. so whenever for any reason i’m like « but you love me so » he normally replies something along the lines « whatever helps you sleep at night ». recently however, he actually admitted it and ik it’s genuine bc he doesn’t normally say it to anyone. so i began wondering, how many times when you’ve said i love you to a girl was it genuine? are there specific people you’d say it to? or would say that to a girl just to get something?
