my best friend betrayed me after YEARS of friendship and it feels worse than a literal breakup. i loved him to death and he threw me away like i was absolutely nothing to him. for NO reason, there was no fight or anything. its been a year and six days since then and i have no idea how to move on from it. i go to therapy but it doesnt help. i dont know how to repair my trust issues, its ruining my other relationships. why am i not over him and what he did?? how do i move on??
