I made a young girl cry because she didn't deserve to be with my boyfriend. Now I regret it.

I (25F) made a young girl cry because she was dating a man I like. I regret my actions immensely. I am so mortified and I don't know what to do. <br><br>I've been interested in a guy (26M) for a few years and I made a mistake by telling him how I feel. When I confessed to him a few weeks ago he never responded. He seemed to avoid me and I felt like a total loser. <br><br>About 8 days ago I found out that he was involved with a new coworker (20F) at his new job. His relationship with her was supposed to be a secret. I was so jealous and angry at myself for not taking a chance to be with him before. I saw that his new girlfriend was on social media (public profile) so I kept looking at her profile and comparing myself to her. I felt so hurt and pathetic that I was jealous of a young girl. I decided to message her and tell her that I had been interested in her boyfriend for quite a while. I told her that I didn't think she deserved to be with him. I was so cruel and tore her down in the message. I basically made her feel like she was worthless and ugly and many other mean things. I was so mean. <br><br>I didn't expect her to respond but she begged me to delete the message and said that she wasn't his type, that she didn't know he was interested in me, that she wasn't trying to hurt me. I ignored her responses and continued to send her mean messages and to tell her what I really thought of her. I didn't want her to be with him, I wanted to be with him. <br><br>I didn't hear back from her until 3 days ago. She told me that she cried in the car and that she was very upset after reading the messages that I sent her. She said that she didn't want me to feel bad and that she just wanted to let me know how my messages made her feel. She said she was sorry that I was hurting and hoped that I would feel better. <br><br>Right after I sent her the first message I regretted my actions. I regret it even more now. I wasn't expecting her to respond the way she did. I thought she would be mean back to me but she's just a sweet and innocent girl who doesn't deserve to be treated the way I treated her. I tore her down and she apologized to me. <br><br>I plan to reach out to her and apologize for how I treated her. It won't be an easy message to send but I feel that I have to.
