why do men always say i love you so early?

it seems in art/media we are told women are the ones who feel so intensely so quickly and push for commitment. however in every relationship i have experienced, men always say i love you first and that they want to be with me. i’m talking 3 weeks or less. this isn’t a brag, because from my perspective, they don’t know me well enough to make that proclamation & so it feels much more like a fantasy is being projected onto me. for a while i thought it was because i was so flexible & adaptable, making it easy for them to see whoever they wanted to see. but as i’ve gotten older, i make a point to be authentic even when it’s not comfortable or popular. and still, even if i tell them i can’t reciprocate the sentiment or that i’m not looking for a serious relationship, they persist. there must be something i am either seeking out or that i represent to them to continue this pattern but i’m not entirely sure what. if there’s anyone out there who can relate to this experience, what’s your perspective? did you feel the need to make a change in yourself or who you date? i’m genuinely asking. it doesn’t feel good to receive this level of intensity when i know i’m not there yet or that i can’t reciprocate.
