help!! i'm in high school so this is all happening over social media of course, but me and this guy recently ended things last week. his ex has been kinda following this whole thing as it was happening like asking my friends about me and stuff, and last night she commented on one of my posts. she clearly hates me but i don't know why bc 1. her and this guy have been over for awhile and 2. me and him aren't even talking anymore!! what do i do?
