Sad about breakup and feeling a loss of confidence

My boyfriend of three years cheated and left me for someone else. I feel like there is no hope for me. Such as I will never find anyone else. How do I stop feeling like this? How do I have hope for someone else to come into my life. I feel like I’ll never be in a relationship again even though it may not be true. I just don’t have any confidence anymore. I hate my body now. He told me how much prettier she was than me and I just don’t love me the way I did when we were together.

People tell me it’s okay because I’m prettier than her and I’m still beautiful but idk. It still hurts and I feel like no one will ever love me again. He always promised he’d never break up with me. He said he wanted to marry me. I believed him too. 🥺 I know I can be independent and strong without a man but I just want some love one day and I feel like it’s not waiting there for me. I feel like I’ll never get married and have kids and all that Jazz

This is me btw and I’m so young to feel like this because I have my whole life ahead of me but I’m homeschooled and I don’t see a bunch of people. I just feel so lonely and I have friends but not guy friends so I feel like I’ll never find my other half. I feel like I won’t love anyone the way I loved him because I loved everything about him. I just want someone like him but someone who would treat me right and I’ll never find that.

My boyfriend called me a leech and told me I drained him of his happiness but I didn’t do anything. I tried to make him the happiest person alive. It hurts to know he truly believes this. I just don’t want to have to know I made him feel like this because I didn’t mean to. I thought we were happy. We always laughed and cut up when we hung out. I had no idea he was unhappy in our relationship and now I’m broken inside while he’s happy with his new girlfriend. I’m glad he has her though. She makes him happy and that’s all I ever wanted for him but I’m still crying my eyes out typing this. It has been two weeks since we broke up and I’m so hurt.
