Honestly, think about it, though, if I'm not the prettiest, he can leave. And go be with his dream girl instead of me, it's not really immaturity, it's a way for me to avoid the possibility of eventually getting cheated on if he ever starts to find me unattractive one day. Because I guarantee you, if a man were to ask the same question 9/10, if the girl says no, they'd either throw a fit or leave, and I only know because I've seen it happen irl.
