Guys Who Don’t Know What They Have

I kind of know the answer to this already, but I just need to vent anyway. I have feelings for this guy and I keep thinking that “if we’re friends long enough, it’ll turn into something.” This thought is completely 100% wrong and I know it. He’s not a bad person, just doesn’t seem like he knows what he wants or just doesn’t want me. He keeps saying that he wants me around, and I’ve been giving him my all, and he dates and talks to other girls. Telling me about his love life when all I want to say is “HELLO, the girl you need is right HERE.” I want to walk away from him I do, but at the same time, he makes me feel really good and we have such a great time together that I don’t want to give that up just yet or at all. Like I said, I already know the answer to this problem but have any of you ever experienced this?
