Dear Best Friend,
Recently, you've been feeling in need of some space away from me and the rest of our friends. I have to admit that initially, I wasn't very understanding. I didn't know what would come of all of this. I also didn't know where you were mentally, and it hurt me that you were able to cut me out of your life without explaining why.
But upon a little bit more communication, I realized that I understood where you were coming from with needing time and space away. Sometimes, you need to change yourself and better yourself, even if that means being away from people because you don't want them to influence who you become too much.
I know you are doing what is best for you, and I know that in the end, there will be more good that comes from this, and I can only imagine this will strengthen our relationship further down the line. I won't pretend it doesn't hurt me a little bit that I was one of the people you felt the need to take time away from, but I also can't bring myself to be mad at you for doing this.
As one of your best friends, all I have ever wanted is for you to be where you want to be in life and for you to be happy being there. If that means taking some time and/or space away from us than I support you 100%. Your happiness is all that I have ever wanted.
Take all the time you need, and better yourself over this period of time, however long it may be. Because I never want you to feel trapped, or unhappy because I decided to be selfish.
I'll be here when you're ready to talk, and I'll be here to support you through this journey if you need it.
Love,
Your person
