Today was a bad day

Today, my boyfriend wanted to break up with me. he said it was because he had a lot going through his mind, and I said I would help him, but he didn't want it. I can understand that, but I don't know what it is. I wanted to rant/talk about it, because I'm really sad about it, but I could kinda feel it was coming. We broke up, and my best friend is mad at him. I also understand that, but still... Anyone want to talk? 🤔
