Dear (insert name),
Instead of getting angry and bursting out like I did the other day, I wish I could have said that I’m disappointed in you.
I’m disappointed in you because I thought this could have gone somewhere.
I’m disappointed in you because you took my feelings for granted.
I’m disappointed because I realized that you will never belong to me because you belong to someone else.
I’m disappointed because you made me feel like I am able to see myself with someone else and then break my heart.
I wish I could tell you how upset I am and how much I miss you.
I wish I could tell you that although we have never met each other, I actually genuinely and sincerely have feelings for you.
I wish I could tell you that I have already got my hopes up.
I wish I could tell you that I started picturing what it’s like to be with you.
All in all, I wish I could tell you that I miss you and I wish things could have turned out differently. I wish that you weren’t such a dick. It’s so sad. I wish things didn’t have to end this way.
