i regret dating a famous guy

i’ve never used this subreddit before so idk how it works but i kinda just wanna rant. i recently found out that he’s been texting MULTIPLE girls through out the ENTIRE time we were together. i thought he loved me, he was the nicest guy i’ve ever been with and he treated me with so much love and respect and would even spend hundreds on me every single time we’d go out because i’m “worth every penny” and that i “deserve it”. i trusted him so much i even gave him my body which i’m so ashamed of because i’ve never done anything like that before (although I’m 21) and i just don’t understand how it was all fake from his side. his ex found out and reached out to me, she sent me screenshots of his chats with other girls and photos of him at events with his arm around different girls and it genuinely destroyed me because i found out on valentine’s day and that apparently she went through the same thing before they broke up. all of my friends warned me about dating a public figure but i just never listened to them and assumed that he obviously wouldn’t hurt me and now i feel so stupid. he knew all about my issues and the traumatic experiences i went through and always reassured me and reminded me how much he cared for me. i don’t know how i can believe/trust a guy ever again, i’m beyond hurt, he found out that she spoke to me and hasn’t texted me since, i haven’t had a conversation with him ever since i found out. he’s not even trying and it hurts because the worst part is that i still deeply love him and care for him. how can i get over it? he raised my standards so much and just disappeared out of my life
