Hello there, hope u guys doing good, m doing horrible advice me in this pls

We were together for 5 years, now m 26 he is 26 as well, we had several breakups for the last 2 years till he faced me with the truth that he completely lost feelings for me for no reason (he's not cheating cuz he has no one on all his social media) so, the last and final breakup was 2 weeks ago, he said that he simply doesnt want to marry someone he doesnt love and he cant even stand the sight of me nor talking to me nor my smile, he said m good i didnt hurt him or anything and he doesnt hate me but also has no feelings for me as he also feels disgusted to talk to me because he cant stand talking to people who he has no feelings for.

Anyway we broke up i'v been doing horrible we were planning for our engagement and everything i even brought many stuff for that day..

The thing is i checked his social media now, he doesnt have many posts, only one pic on Instagram and I commented on it years before "proud of u boo" now as i checked he actually deleted my comment, and that obvious but the thing is .. guys, how do i stop feeling like a fool? Regret is killing me m not eating not doing anything except for crying cuz i loved him so so much i feel like a clown 🤡, i feel like it was only me living in delusions for years, there was no love only me doing a show on my own in this relationship, guys i feel disgusted with the whole thing i end up vomiting at night everyday.. apparently he's doing just fine cuz he doesnt even have feelings for me, which hurts me even more that m the only one suffering..
