I think it depends on the person. I’m dubious of too much I love yous from most people. It’s got to feel sincere. And if it’s thrown around, it often doesn’t ring true to me. Having said that, I know some people like yourself who are filled to the brim with I love yous and I absolutely believe them and am endeared to them!
As for me, I’m generous with compliments, but in general sparing with “I love you!”
I reckon I’m not likely to say “I love you,” but am very apt to say “I made this mixtape for you!”
