Sure! Here’s a revised version of your message:
"I texted him around 5:00 PM to let him know that I was going to the Mosville festival. He strongly denied it. I then told him I wouldn’t be going anywhere. After that, he texted my brother, saying he was coming to Monsterlus and asked him not to tell me about his plans to prevent me from going to the event. You know how siblings are—my brother sent me some screenshots of their conversation. It turns out that this guy drove all the way from Middleburg to Monsterlus just to try to stop me from attending!"
