Fateful Email

You would think that with all the days going by... It would get easier. It doesn't. I've never had my heart broken before. He was my first... And I miss him so much. You know? It makes it harder because of all the promises we made to each other. "I'll never leave you." "I love you." "I'll always be there for you." "I'll protect you... I promise." "I swear... I'll never make you cry." And it's so weird. Before all of this, we were best friends. I know him so well. We were so happy. The awkward smiles and innocent looks in his eyes. He tried to hard to be tough in front of everyone, but he wasn't. Only I know his true side. He trusted me and as far as I know, I never let him down before. So why now? Why's he doing this? He said something happened. I dont know what, but it was something...
Before all this, we told everyone that he was my adopted brother, which he kinda was before this. He lives with me, eats my food, sleeps in my bed... plays my games. ^_^ He said to me, he just wanted to be my brother again. I dont understand it. See, look. This is the email he sent to me:

look scince you haven't been emailing me back i'm gonna be real with you i've enjoyed our time together but lately i've
been thinking and i think we should go our own ways no hard feelings or nothing but when i say i love you it just dosen't feel right, nothing against you, but at this point in time i can't return those feelings
like i used to. my heart is aching right now
and i know that yours is too, i want to be your brother again, but i can't continue to be your lover, not in the state i'm in right now. i want to leave a chance of us happining again in the future and maybe there is but as it stands right now we've got to call it quits. if this message reaches you before i do just know one thing even when we're apart if you need anything anything at all contact me i'll be there no matter what, thats on my soul. like i said if you can contact me before i get to you
just know you've always got someone watching
your back. love you sis, stay safe,and remember if anything is bothering you, email me at this address this is my personal
connection-_____________- take care of yourself kid, i won't say good bye because i'll see you later.XCS

Keep in mind, this came out of the blue. No arguments or anything. I dont understand why.
I just want to get this off of my mind.
