Am i the asshole for making friends after the breakup?

We’ve been together for 2 years and 5 months in a long distance relationship. We still met eachother but not that often because he always got some excuses. At the end we fought alot and barely talked to eachother. A month ago (12.02.2026) I texted him and apologized for everything just to get a message like this: I’m sorry but I lost feelings two months ago. Quick reminder I felt so lonley in that time even though he still was with me. So I added other (boy) friends online. Not to make him jelous or to replace him. No, I just needed some people to clear my mind. I met them randomly and it worked. Me and my friends played online games together and this was my first time in a while I actually had fun again and could laugh. I just liked them as friends and there would never be more. Well and so did he. The diffrence between my boy friends and his girl friends was that his friends were local. So he started texting with that one girl and I guess he started catching feelings for her. She went to the same gym as him so they also met eachother. More than we did. I didn’t even know until he told me 2 months ago. He said that he would forgive me and that I should forget him but I can’t. How can u lose that fast feelings for some1 you’ve been together for almost 2 and a half year? My intentions were never to met some1 else I just felt so lonely. He also told me that he will block me when he got with some1 else and 2 weeks after our break up he did block me. He also targeted this girl in his insta bio w a heart. So you’re telling me He got together with a girl he barely know 2 weeks ago we broke up? After a 2 years relationship? I don’t get it. While he is happy with that girl. Im siting here all by myself and suffering in silence. I told my mom and friends and it helped a lot but it’s not enough. As soon as Im alone Im not feeling good. 2 days ago I fainted because of the stress and pain. even the doctor said its because of my heartbreak. How could you just leave me like that? Even after a month of no contact Im feeling horrible and you are just happy with your new girlfriend? It’s not fair. For everyone who is actually reading that: thank you. I know the text might be a little messy but so am I right now and it describes my feelings pretty well.
