i don't know what to say here. i've been dealing with a lot over the past year and i've been really hurting for a long time. there's a lot that i wish i could tell you or talk to you about, but i can't help but feel like this is truly the end of the line. 
i hope you are well, and i'm sorry for bothering you with my problems and for trying to force a friendship to remain. it's not fair to either of us and i'm sorry that i didn't see that before. 
i guess i just didn't ever want to fully give up, and honestly, i still don't. i just really miss the happiness that i had before i enlisted, and you were a major part of that. i've made a lot of mistakes in my life, but i'm thankful i was able to share some time with you.
truly, i'm sorry for everything that i've put you through.
i wish you nothing but success, happiness, and wealth in your life.
maybe i'll see you again someday, but until then,

goodbye.
