My ex fiancé left me 3 weeks before the wedding
i was engaged to my ex and we were together for two years. Before me, there was another girl in his life .. the only girl he had ever dated in middle school.. and from what I knew, he had been attached to or after her for around eight years after she left him.. During our relationship, there were a few times when I caught him stalking or checking up on her, but every time he begged for forgiveness, reassured me that it meant nothing, and insisted that she was not important to him. What made me believe him even more was that throughout our relationship, he would speak negatively about her, slut shame her, and call her really harsh names in front of me, so I genuinely never thought he still cared about her in any way.
Then after two years together and getting engaged, the moment he left me, he went back to her. That is what keeps eating at me because I can’t stop wondering what that actually means. Did he truly love me and our relationship, because there were a lot of things that he did that would make anyone think that way.. or was I unknowingly just a placeholder until things with her happened again? Does he genuinely love and respect her?, or was there something else behind going back to someone he seemed to hold onto for so many years?.. i can’t get it off my head because even that girl knew how much he slut shamed her with everyone and she is still with him despite all this.. mind you she used to be my friend but after a few times she dissed mine and his relationship, and made fun of me in-front of others, i ended it with her.. now they both are going in vacations and posting each other about how happy they are! i am over him but not over this situation.. someone please give me their perspective
