Dear my best friend's boyfriend,
I already know you much better than you know me. I've stalked you (and probably all of your ex-girlfriends) on every form of social media that I could find. I know just as much about this relationship as you do and probably even more.
Now, you're probably afraid that she tells me every single detail about your relationship. And the truth is- she does. It's a girl thing. We really just can't help ourselves. Every single relationship we are involved in is a group effort, and you're just going to have to get used to it. And I hate to break it to you, but you can't get upset about that because I have already been in this relationship way longer than you have.
I was there when she first saw saw you and thought you were the cutest guy she had ever seen. I was there when she first started talking to you and needed to be reminded how beautiful and perfect she was so she didn't have a panic attack and forget how to speak. I was there when she decided she liked you and when she was freaking out wondering if you liked her too. I can tell by the smile on her face when it's you that's texting her, and I can tell by the wrinkle she gets in her brow when you say something that upsets her. I know the way her brain works even better than she does and I can always calm her down when she's acting crazy.
So don't worry- I'm on your side here. If she's happy, then I'm happy, and happy is what you make her. I'm rooting for you guys to make it because I don't want her happiness to end. She knows I'll give my honest opinion when she asks me for advice, and that's not always what she wants to hear. I'll be the first one to tell her when she's overreacting to something and I'll never get tired of telling her what a good guy I think you are for her.
I may like you, but I'll never really think that you deserve her, and I'll probably never completely trust that you'll never hurt her. It's nothing personal. I've just seen her go through countless ups and downs with boys that have come and gone, so you can't blame me for being a little protective. But for now, I think you're all right.
If there's one thing about her you should know, it's that you are a lucky, lucky person to have this special place in her life. You have somehow squirmed your way into her heart, so you better not screw this up. There is not a doubt in my mind that you care about her, but I can promise you that I care about her more. So take this as me formally giving you my blessing to be with her. Just don't forget, it always has been and always will be best friends over boyfriends, so you better not try to steal my girl from me.
