please help

hi, you guys I’m 18 years old and something recent happened to me actually today that really just destroyed me basically I reconnected with a guy that I knew back in 2025 and we had already been talking now for a while. We’ve been hanging out. He met my mom. He talked to my mom. Had a conversation with my mom. And we were good he made me think that he was a good person. Yeah he had some red flags but the person I knew in 2025 was a good guy and would never break my heart so one day we end up hanging out and I have sex with him we were very intimate. He told me things that made me feel good really good actually so after that day, it was good. We were still good. We ended up hanging out again and it was really good. We were intimate again and right before we went our separate ways and we left. He gave me a kiss. I told him to text me. He said he would. He didn’t text me for three days after we hung out and we’re intimate and then I check his *** repost and basically just reposted a *** saying like that he got his girl back but he’s not talking about me. He’s talking about someone else and then it also said in the *** I’m quick to leave a *** which obviously referring to me I’m guessing so he left me after we had sex after I gave up something that I thought would bring us closer so now I’m left unanswered questions and broken heart and confusion and feeling like I’m not worthy and feeling like I’m not good enough and I feel ugly and I feel gross. I feel ashamed and embarrassed and ridiculous and pathetic and a loser.
