Couldn't you just Deny the accusation or did the X have some proof she could show your friends ?
Did she post pics of you dressed or show off your clothes ?
Did you not want to deny it ?
How exactly did your friends react ? Did anybody ask you if it was true, if so what did they ask ?
Did any friends support you by just saying they didn't care ?
Since so many of us worry about this just trying to understand how these things played out.
Thanks and sorry for bringing up difficult memories
