If blogger and reader had a relationship and you had to follow the normal breakup protocols before breaking up(stop following).
The top reasons could be
1. Its so difficult to reach you ,you dont let me in (if comment section is difficult to find)
2.You dont express your feelings(if the reader doesn’t comment)
3. You don’t value my feelings(if blogger doesn’t respond)
4.You give others more importance in your life(if the blogger doesn’t reply to your comments specifically)
5. You are always about Me Me and Me and not Us(if blogger talks mostly of himself)
