Search Results: losing a first love

My first time was 4 months ago at the late age of 20. I found out he was cheating the whole time and then I got dumped for the other girl; I got blocked too. He said he has no regret about it and never loved me.. started laughing. Then he told me who he really was, showed me his old childhood picture and explained how he's been waiting for that moment. I didn't recognize him because he looked way different back then and I was fat as a kid.

Flashback to March 2009 (I was 12; he was a couple weeks day of his 13th b-day):
Both of us were having a miserable time in 7th grade. I framed him when we were close to making out on the hallways and I saw the jerks were stopping by to harrass us and tell everyone in the class. I didn't want to get humiliated anymore. At the time I was basically kissing the boy that no one liked, whom they all called a loser while my nicknames used to be Orca, Moo or Buffalo.
He got more bullied than before and his reputation got worse after that incident while I stopped getting picked up. Though I noticed many were just being my friends out of pity mainly; they believed my story. We switched school the following month, not to be heard from again.
However, I told the truth before my HS graduation... losing a couple friends that very day.

Present- day:
While dumping me, he also admitted to punching the hell out of one of his former bullies (the ringleader) and leaving the guy on the ground with a broken nose, then spitting at him. Before that he asked him ''do you remember me''. The guy said no, he told him who he was but the guy made a sarcastic comment and laughed.

As most of you know, I used to love Fire Emblem. But now, I kinda am starting to lack interest in it. To the point I no longer want to hear about it. I'm more into YT (Yoko Taro), Magi (finished anime back in 2015. Reading Manga) and Stella Glow <3 Also the fandom kinda... sucks a lot. Again, there's this other cosplayer on Instagram who's going crazy against me. She said "I give her anxiety" and she had a "panic attack in class" because of me. Huh? Wtf. First off, you (her) block me without warning me about my actions. Second, your work is trash (facing my idols'. Oh no, we can't compare a nimble person to Amazing gods). Thirdly and lastly, you've been rude to me indirectly.
Back to the Fire Emblem thingy, I'm going to AX next year. I costested Mae from FE Echoes as a thrown over cosplay and everyone is liking it. But I'm backing away from anything FE because I actually didn't really like the games but I appreciated/liked some characters. There's this friend I met from the cosmunity, who still doesn't know I no longer want to cosplay Fire Emblem and LOVES my Mae costests (this girl is really nice and fun to talk to btw). So she thought about doing Mae x Celica at AX. I'm actually shy to tell the truth despite my lack of interest in Fire Emblem.
I love YT, Magi and SG more!! Help? What should I tell her without being hurtful?
idea: I thought about cosplaying A2 (favorite character of mine) with her and her twin as their two all time favorite characters.
back at it: I don't really care about FE anymore. I mean, I have better franchises and fandoms.
PLEASE HELP.
