Is 3 weeks long enough

I’ve been hanging out with my friend & talking to him for 3 weeks . We basically have been seeing each other everyday type of thing . But the other night when we were laying down just talking & he had said something like “ do u think your falling in love with me ? And I replied : I like you a lot & I can see it potently growing more into love . But last night he said he loved me 😕 and I thought maybe he was just saying it in the heat of the moment but he told me it again this morning & I told him no u don’t !! You probably have love for me but you don’t love me . And no I don’t say it back , but I do feel like we have a strong connection, like as if we aren’t new to each other . But Should I RUN 🏃‍♀️ or see what plays out ?
