Guy's Behavior

Is there a possibility that my male childhood friend had/still has a crush on me?

I have a guy friend that I first met when were about 10/11 years old. He would come to my house and hang out in the backyard or we would go to the park. He also gave me a diomond bracelet when we were kids. Like an actual bracelet real jewelry. We also hung out a bit when we were teenagers. We lived in the same city but went to different schools. Well years went by and we went our separate ways until about 2 years ago. He added me on facebook. Him and I have mutual friends and when I told our mutual friends he gave me a bracelet when we were kids told our mutual friends yes he remembers. We started snapping each other and met up at the one park and he talked to me for over 3 hours straight which is unusual for him as he has always been very quiet and even our mutual friend was surprised he talked that long. We hadn't seen each other in years though and it's like we just picked up where we left off. His attention was on me the whole time. I know when were kids we did admit to liking each other. As far as I know of he has only had 1 relationship in the past as he is very quiet, kept to himself and a bit shy. Is it possible he may still be crushing on me or am I reading too much into it?
