I Am Having Friendship Problems

[b]Long ramblings about friendship... [/b]

Yesterday I told my best friend I wanted to go to a concert with him today, and he told me to let him know at what time so we could go. Today he texted me to let me know that he was going with a group of people whom he was playing volleyball with on a company sponsored event today. Amongst the group are people I don't like. Bullies and people that have caused trouble for others by lying. He asked if I was going. I asked at what time he was planning to go, read his reply, and that was it. I chose not to go but said nothing. Hoping he'd text me again asking if I was there, let me know he had arrived, or at the very least ask if I was going. But he never texted me again. I've seen how he's a completely different person around them. How he has fun with them and enjoys talking to them. How he doesn't care about the wrongs they've done and still do. He's the type that wants to be liked by everyone. And deep down I know he has a bit of a bullying side in him. I've heard him say things I disapprove of when he thinks I'm not listening. I didn't want to be in the way. That's how I felt. So I staued home. He knows how I feel about them. But that doesn't seem to matter to him. I sometimes wonder if he cares at all about how I feel. If he wonders about what I'm thinking. I like to spend time alone with him, because he's a different person, better. But which is the real him? Would he be better off without me? Would I be better off without him? I've felt myself wanting to pull away from him. But, I've stayed. For how long? Is this really friendship or are we doomed to go our separate ways? Only time will tell.
