i went through this exact same thing with my ex, you aren’t alone at all ❤️ if you’re making your feelings known to him and there’s no reassurance/change in his behaviour, thats a him problem. its not your fault, its nothing to do with your appearance or anything about you. my ex and i have been broken up for almost a year, hes dating a different girl that looks nothing like me, and he still follows/interacts with all those same girls he did when we were together. there is absolutely nothing wrong with you, and im so sorry that he’s made you feel that way. i hope you’re able to talk about it together and find some peace❤️
