Was I Meant to Stay?

my mind is racing with these thoughts of him. these thoughts that I should have let go of. these thoughts that are not meant to mean anything. at least not to him. But even though I fell for someone else, and I have no place in his life anymore. I still want one. is it wrong for me to still want to be in his life even if we are just friends? is it wrong for me to want his comfort even though I didn't want it before? So should I have stayed?
