If a guy says "I love you" after like a day into your relationship, do you run?

He's implying that you should never have children in order that your genetic material never has to enter the human gene pool to prevent stupidity of such magnitude from occurring again. He believes, for the good of mankind, that the best way to do this is to ensure you continue to use contraceptives for the next thirty years while you are still highly viable for childbearing.

On topic, like another poster said earlier, he was likely screaming it at the top of his (mental) voice every time he saw you for the last nine months. I would put money that he has, more or less, put you on a glorious pedestal in his mind that you'll probably never be able to match. Life, however, is made of a series of compromises until our sense of self is lost in the midst of the maelstrom of human pettiness and disappointment. C'est la vie!

I agree completely with your definition of love, but I do still believe that it's possible to have that kind of connection after a relatively short amount of time
