To the guy who is lucky enough to be trusted with my best friend's heart.
Congratulations, you have my best friend's heart. She has seen something in you that makes her want to take you as her partner. Listen closely, there is something that you need to hear.
You have something priceless here, do you understand? I mean, something really priceless. This girl has helped me through my darkest days, my best hours, my weird emotional moments, my awful snort laughs and everything else in between. She has even seen my ugly snot-snorting cry, and that's traumatizing for anyone to see. I am a very difficult person to live with, and she has been there through it all, with no complaining and nothing but grace. She has been my rock through everything, I keep nothing from her. She is literally my better half.
My best friend deserves nothing but the absolute best in life, and she thinks that you are the best choice for a partner. She has high standards for guys but isn't nit-picky about the romance. So since she probably won't say anything, I will. Go above and beyond for this girl. Do the small stuff, like holding the doors open for her. Buy those little candies that she likes. Write those little letters that hold the inside jokes or has a compliment written on it. Her heart belongs in an older generation, so be unique and don't be romantic solely through texts or Snapchat. Go out of your way for her, because I PROMISE you, she will do that stuff for you without anyone needing to say anything to her. She will invest herself completely into this relationship, and if you aren't willing to do the same then you aren't worth her precious time.
She has been through so much and has worked very hard for what she has now. She is a stunning woman with an old soul and made out of nothing but old school class. For you to have something so precious in your life, I hope you realize how lucky you are.
I knew about you even before you have even thought about dating my best friend. I have seen the text messages, heard the stories. I know way more about you than I do about the stuff I am learning in math class. It sounds scary, and it sort of is. For you at least, because you need to get one thing straight. I am on her team 100 percent. If you set even one toe out of line, I WILL hear about it, and you will be on my most despised list. This girl is a huge part of me, you need to realize this. Her pain is my pain, her loss is my loss, her happiness is my happiness. She is my person. I hope you have someone like this in your life because then you can understand slightly how much I love my best friend. You hurt her, you've hurt me then and I have come to learn that I actually can hold grudges.
You have her heart, take good care of it. Don't abuse the power you have over it, she doesn't deserve that.
Sincerely,
The Best Friend
