Can a man fall in love with a woman after one month of dating?

I started dating my boyfriend a little over a month ago, and we have been inseparable since then. He's amazing; he tells me all the time how beautiful I am, makes me breakfast when I stay over, calls me everyday, and more. Two nights ago, he told me he loved me. I love him, too, but I'm just confused, because I've never had a boyfriend (let alone a decent one) tell me that he loved me so openly and right off the bat. Is this something of a concern, or am I just being jaded and should shut the hell up?
