Most Helpful Girl
First of all, I don't think he's playing you. I don't have direct experience, but am going through something similar. His history plays a really large part. Obviously, I don't know him, so I don't have a right to judge. But, it seems that he may have emotionally invested into things multiple times in the past, but they have all turned on him (a lot of it probably family). So, as of now, it scares him to be in a relationship with you.
He probably is mentally aware the he can trust you, but there's an intuitive feeling telling him to not do it. I think he truly cares for you and wants you to have the best in life. He wants you to be happy and wants to be the man to make it happen, but feels like he can't. He's fully aware of his history and problems. Most likely, he doesn't want you to be brought into his "dark side."
This guy is really sensitive and needs committment. It's up to you whether you want to be the rock for him and invest your emotions/time. I think he needs reassurance that you'll be there and that his feelings won't be betrayed. Don't get me wrong, I think you reacted naturally with his indecisiveness and that you guys should talk. I think he cares about you so much, but can't express it due to his own insecurities.
