What does it mean when your ex starts being touchy feely with you?

Anonymous
my ex and I have always remained friends since we broke up in 2003. And anytime we've seen each other we talk for a long time have always kept a respectable distance between us when we do talk and when we hug good bye its always been just real quick and like as minimum touching as possible. I've been really busy so I haven't seen him in about 6 months. Me and a few friends got together and he was there. We all talked all night and throughout the entire conversation he would find excuses to touch me whether it was patting my arm or my hand or leg. He kept going back to the past and how I'm the only girl he had dated that he's kept in contact with and whatnot. When we all got ready to depart from our get together he gave every1 hugs all were that one arm over the shoulder pat you on the back real quick then move on kind of hug. Then he gave me a hug and it was both arms around me squeezed firmly lasted longer than the other hugs kind of hug. He left and bout 10 min after he left he called me to tell me the clouds outside look kind of like heavens peeking through and its really beautiful when you get outside look at it. Totally out of character for him. And then proceeded to keep me on the phone for another 15 min then the conversation was ended with I really hope to see you again soon. I'm really confused because even when we were dating he was never that touchy feely and never gave hugs like that to anyone. That was just the way he was and seeing him interact with every1 else it was that way. I'm just really confused.
