I don't know where to start …
But maybe I can start by saying :

Thank you for been my favorite person

 Thank you for been a mirror that reflects a better part of me 

Thank you for loving me everyday even on days wen I'm undeserving of your love

Thank you for been the definition of gods love for me

Thank you for loving me the way you did, thank you for loving me in the purest form

Thank you for always looking out for me, I still see you looking out for me

I am grateful I got to experience you, you saw for me even more than I could ever see myself,I'm grateful to have known you and to be Loved by you , you are the closest to heaven that I would ever be
