He's fickle and always changes his mind of who he wants to attach himself to. Don't rely nor trust that this is more than a temporary thing and once he finds that you've grown stale he'll find someone else to surround. He doesn't mean to, but he jumps from person to person without loyalty. Once who I would call a great friend is now what I'd call an idealist without the mind to keep track of their ideas. Don't let yourself get hurt. Please. There's people out there who've cared about you longer, who've always had your back and looked out for you. I don't look for you to acknowledge it, never have, you rarely do. But there's been at least one guy who will always be your safety net; someday you may see it.
