You gave trust to the wrong person

Well, a while ago I was talking to a girl on Tik Tok, and we confessed our love for each other. Then she sent me her pictures via Snapchat, and we exchanged pictures and talked a lot at night, but later I found out that she came to me, and her new boyfriend came to me and said, "Don't text her again," and I did what he said, because he gave me a lot. From the conversations, I told him everything about me.. .. I did nothing but love her.... Did I do something wrong? Well, her name was Zeinab, but I hate her so much now, but I don't know whether to love her or hate her. I just don't want to remember her, but I can't remember her every day and cry A lot. I was even thinking about proposing to her in the future, but something happened.. The end {The story is true..}
