how do i get over my cheating ex?
i have no idea if this the right place but this is relationship advice and i guess this is a relationship? for some backstory i (21m) had met my now ex boyfriend (23m) through an rp online (its cringey, i know) in november 2023. before we dated, i had just gotten out of a relationship with a girl who completely ghosted me by blocking me on every social she knew i had. my ex boyfriend knew of this and we didnt start dating until a year after we met.
everything was fine until maybe november 2025 where he also started to ghost me, which i was extremely upset about seeing as he KNEW how much i didnt like being ghosted and it took me until early january of this year for me to break things off with him because of how hurt i was, especially since he was there when my ex girlfriend ghosted me and saw how badly it affected me mentally. come to find out through a friend of mine that he already has a new partner and is even planning to move in with them through TIKTOK of all places. this has made me extremely upset because while we were together, he wouldn't even entertain the idea of us moving in together, only for him to turn around and decide to move in with someone he only just recently started dating. my friend did some digging and apparently my ex and his new boyfriend had been planning on moving in together for months which just made me even more upset because WHY was he moving in with someone while we were dating??? and again he wouldnt even entertain the idea of moving in with me throughout the almost 2 years we were dating. but ultimately that led to me meeting someone who had said that my ex was trying to get with their friend in august of 2025, and they ended up setting me up with the friend in question.
after talking to their friend for a while, i got the confirmation that my ex had indeed cheated on me. while nothing physically had happened, he was still in a poly relationship with two other people WHILE we were dating in march of 2025. i had already gotten the idea that he cheated on me but something about getting confirmation that he actually did cheat on me just broke me. ive thought about dmming him on an alt account to tell him how horrible of a person he is or telling his new boyfriend that my ex is a cheating bastard who doesnt deserve to be in a relationship but ultimately i know that none of that would make me feel better. i wanted to be friends with the people my ex cheated on me with but i just couldn't deal with the fact they dated my ex boyfriend while i was dating him. i dont blame them for anything that happened as my ex lied to them about my existence and only told them he was dating someone until after the three broke up.
i am in therapy but i havent really talked to my therapist about it in full detail and i dont have my next therapy for a while due to issues with my insurance, so i dont really have anyone to talk to this about besides strangers on the internet. i just dont know what to do or how to move on. i WANT to move on but he's ruined so many things i like because all i can do is think about how he cheated on me every time i see something he liked. its gone as far as that he ruined a POKEMON for me. im sorry if this is rambly but i dont like bringing this issues to my friends as i hate feeling like a burden. i just really want advice on how its possible for me to move on. i know im young and i have plenty of life ahead of me but i dont know how to get better NOW. ive done everything i could do to distract myself from it but i just dont know how to permanently move on. any advice would be very nice, i just want to get over him and get rid of this image of him hanging over my head.
