Dear My Boyfriend's Ex,
I don't want to come off too strong, but I'd like to start off with thanking you. Thank you for in whatever way losing him. Thank you for messing up so badly that he is no longer yours. As much resentment as I have towards you, I also appreciate that at one point in his life you took care of him for me. You may not be on good terms, and-- for my sake-- I hope you never are, but at one point you loved each other and for whatever reason it ended and thank god because he's mine now and I won't ever lose him. Although I'm happy that for whatever reason you aren't together anymore, I'm also angry because without even knowing it you've wrecked pieces of him. There are certain things he doesn't do because he remembers how mad it made you and assumes it would be the same with me. There are times when he's afraid to even laugh at a dirty joke with his friends because he's afraid I'll get mad at him like you used to. Without even knowing, you've trained him to be afraid to be himself. Slowly but surely I'm breaking that shell, but it's hard for him to understand that it's okay to laugh at a joke or spend time with his friends. He always expects a fight when he is out with them. Although this bothers me, it can't compare to the fact that thanks to you, who for all I know could have been his first love, I plan I being his last which to me is a heck of a lot better. Thanks to you he's mine now and I will treat him right and I will make him happy and I will care more about his feelings than my own. He's the one for me I've known this for some time now, so thank you for letting him go, because I never will. And when the day comes that you look back and you miss him and you regret letting him go, forget about it, because he most definitely is the one you let get away and he's never coming back..
Thank you,
His One and Only
