Regret
There's no night that passed that I didn't regret what I did. I am a terrible person. And still is.
Time has passed but I will never, ever have my peace with you as long as I never apologize for breaking you into pieces. I am very sorry for what I did. We we're kids back then, immature and non-thinking of the consequences we'll face for our actions.
I cannot believe that I managed to do that to you.
If you're happy with somebody else, you don't have to worry about me braking a relationship where you are already having your own share of fun. I just have to make things up with you. After that, if you want to lose touch with me again, it's alright. I'm fine with that.
Once again, I'm so so sorry, I am a terrible person and I don't deserve an understanding person like you.
