Dear ex-best friend and ex-girlfriend.
I did not see any of the following personality traits back when we were friends and I ignored all the red flags when we started: unnecessarily jealous, controlling, mood-swinging, bipolar, disrespectful, liar, cheater.
Breaking up with you was difficult, felt like letting go of a hot rock that burned my hands, but I fought eagerly to keep with me. Two months later you came back out of nowhere calling me, texting me and playing mind games that bring back feelings of hope, pain, uncertainty and keep me wondering and confused. But you know what? thank you for doing so.
Now I realized that I've been dueling for the person I felt in love with but not for the person you are today. I owe an apology to MYSELF for letting you take control and make me change things I like. IT IS ALL MY FAULT because I could've left but I stayed. I hope you can resolve those inner issues that originated years before I met you, that way no one else will have to deal with your emotional baggage. As you said, you've never been able to sustain a healthy relationship, now I understand why. My despair and suffering showed me that I need to work on my self esteem and I'm working actively to become a better, stronger version of myself because I am also far from perfect (but I would've never cheated on you). Thanks to you I realize that I should never make anyone responsible for my happiness. I care about you deeply and I hope you find the answers to all of your dilemmas just like me. I have no regrets and don't hate you, you are just not what I need. If I don't answer your calls or texts is not because of you, I do it for myself. I am the most important person in my life, but I forgot about that when we broke up. I thank you for all the good moments we shared. Good luck, no hard feelings.

Forgive to let go. The happiness in your life depends on the quality of your thoughts.
