Dear J,
I know its kind of too late to tell you this but I did love you. That does not change anything, but pls know that I love you too.
From the beginning u knew that I had trust issues, yet u still pursued a relationship with me. Thank you for everything.
I was nothing close to the perfect girlfriend, but I did love you very much. I only broke up with you bc I didn't think that this would work out.
I m sorry
-your ex gf
