How long does it take for someone to fall in love and how do you know you are?

For me, it was love at first sight with my gf. I knew that it was love because it was like no other woman existed. And I still feel that way. And it’s only grown. When I’m not with her, I am thinking about her. When I’m with her, I’m at my happiest. And I feel like the luckiest guy in the universe ALWAYS.
