I believe in love at first sight, but not in the form that most people think of when they hear that expression.
I am a very intuitive person and can read a person easily, sometimes without ever hearing them speak. There have been two "loves" in my life. For both of them, I knew it instantly.
The first was my very first serious boyfriend in high school. I met him at work. We didn't go to the same school at the time. He walked in while I was working. Yes, he was very good looking, but it wasn't because of that. I saw his goodness immediately. He was the most incredible human being I have ever know. We loved each other fully and completely. We were destined to be together for the four years we were blessed to have with one another before he passed away. He absolutely changed my life. I wouldn't be alive today had it not been for him. And if I were alive without him, I wouldn't be who I am. I'd be a shell of myself. He was my angel.
The second was my husband. He said I saw him once before I saw him for the first time in my POV. He said he was checking out my butt, I saw him, and I gave him a dirty look. That's very possible. But, what I remember is seeing this big lug talking to a guy I was dating at the time. I saw this man that seemed to be a great person, just by looking at his face and body language. When we'd go out with the same group of people and I was dating the other guy, I couldn't stop looking at him. Watching him. Wanting to talk to him, but being too shy to do it. It wasn't because he was cute. He was cute, but he wasn't even my "type" at the time. I was just fascinated with who I felt he was. And I was right. I love him more than life. I always will. It took a while for us to get together, but when it happened, it was strong.
Call it love at first sight or call it intuition. I believe it exists, but you have to know what it is. Inside, you know when it's lust and when it's love, but you have to be willing to be honest with yourself. That's all on you, not on the actual "thing". And love truly does exist, but you have to be open to it. You can't ever see anything that you don't believe in.
