Why you no longer friends with so and so

 "Because I was tired on holding on a friendship that was one sided, and I just let it go because clearly the chemistry was no longer there, we can't keep people who don't want to be kept, and it was breaking my heart to see that I'm the only one who was putting an effort, but I decided to let it go and give her space and let her enjoy having other friends because she was happy with them and I am not a hater I'm just happy that she is happy with her friends "
