Last month, he asked me to a 2 day concert with him. Work screwed me over the first night since they didn't give it off, so I was stuck only going the 2nd day. He was disappointed but still looking forward to having me. I met his guy friends at their hotel (I was the only girl) and once point overheard them talk about another girl that they hung out with the first day. And in line, someone recongnized Blake and asked him where the other girl was from yesterday. When I had a chance I approached one of his friends (let's call him James) about it and he said she's a friend of his and him and Blake are friends with her, but that he wasn't here for the 2nd day. James showed me a selfie off himself with her, and mentionned her name. She was very average looking and. I stalked Blake on FB the next day and he added that girl on FB, while I don't have him on it.
A few weeks ago when Blake texted me randomly late at night, I decided to pop the question for another music festival. He invited me to the last one, so I thought it was ok to ask. He never responded. I saw him last week and everything was normal, and didn't bring up the concert again.
The festival just passed and I saw on Instagram today he was tagged in a photo from the festival with that girl and some other friends (3 girls and 2 guys in total). So he totally didn't bother going with me to this one it seems and picked to hang out with this girls and her friends I guess. I'm surprised because Blake and a good looking guy and she isn't nearly as great. I'll be hearing from Blake soon as usual.. what should I do?
