drop the guy, immediately block him on all socials (take necessary screenshots to explain to your friend) and dump his mfin a**, he seems to be that pick me up guy so not worth it.. he runied ur friendship..snitched behind ur back..a literall as&hole...wipe ur tears, dont cry, dont blame ur self okay...even tho ur relationship with her is in shackles...she thinks u betrayed her rt but all u have to do is tell her everything in detail, maybe she got a point that she said he isnt a good guy only to you and didnt expect u to tell anyone else but explain to her that he persuaded u to tell him and u did not had any ill intentions behind it, she is ur rind u know her she knows u...even if she is a lìl angry rt now...solve this by properly communicating, start by telling her that u want to solve this matter in a mature way to secure and reestablish ur relationship back..be strong and no more tears.. good luck ❤️
