Love at First Sight

I am 37 years old and have been looking for “Mr. Right” for a long time. Two weeks ago I met a man who feels it was love at first sight, and we want to get married. I’m torn about it, because I also feel like I’ve fallen in love with him, but it’s been such a short a time. Does that matter, and does Judaism have a way to tell if love is really love? He’s a nice Jewish man and I don’t want to lose him but also don’t want to do the wrong thing.
