I sent her an e-mail saying that I would never love anyone as much as I love her.
Afterwards, I started making a list of what I now know:
I know that I was genuinely in love with her. This was established not by how much I loved her but by the fact that I wanted to kiss her and hug her and hold her so badly.
I know that she is not in love with me and she will never be. I have never been and will never be mad at her for that. It has caused me much sadness but never anger.
I know that I will never love anyone as much as I love her, even as much as I love him. I have placed her on a pedestal and as time passes, things will be different but she will always be my standard.
I know that everything I felt for her was not because I was in love with her. Not being able to be with her, does not change how much I love her or how much I care about her.
I know she loves me, because I am her best friend. When I first told her I loved her, she ended her letter by saying "love, love, love", which just makes me love her more.
I know that I love him very much and it is so wonderful to be able to say that I found a true gentleman.
I know that we will have a great life together.

I know that I am so incredibly lucky to have her and him in my life.

That's all I need.
