This is a throw away account cuz i am in here with other name. My avoidant (28m) who left me is seriously panicking. He keeps trying to follow me on instagram. He wants to remain friends which i obviously couldn't cuz of my feelings. He starts spam my dms about how shitty he is, how he lose everyone and then talk about suicide. I tried to ignore it but then he called me 2 times in a row. All he wanted was to be friends again. All sobbing and crying (which is good for him, i don't blame him) but ofc i can't go back being friends. Cuz i am heartbroken. Why do some do this? How can they want someone just cuz they cared but not love them back?
