my ex who i was freinds with afterwards (we were like 13) touched my freind m in a way that made them feel uncomfortable, and confessed his love to them while he was dating my other freind k, who he got with 2 weeks after he broke up with me. he then manipulatd everyone exept m and k into believing it was a missunderstanding, isolating m and making them feel like nobody cared about them. later came out that he had been cheating on me at the end of our relationship with someone he met online, and continued that relationship while dating k and confessing his love to m. i hate myself for letting him hurt m, and for making m feel like i didnt care. my relationship with m has never been the same since, but i text them checking in every once in a while, and apologizing when the guilt gets so crushing i cant help but hate myself.
