Hi bright- it sounds like you had a really fun trip! You seem to be in good place with yourself and you would have had the great time with or without H's presence. That seems healthy to me.
Your h seems to be doing some reflecting. I wouldn't dare try and say what he is possibly thinking about however it seems that the times he was around with you are your friends he was aware that he would be seeing you. These were not chance encounters I think. Also his abrupt leaves seem to be a sign of some inner confusion- turmoil perhaps that makes him have to physically get up and leave. That is not a reflection on you - rather it would seem a reflection of the confusion in his mind.
I am so pleased your interactions were positive and even more pleased that you had fun and enjoyed the time away. I guess for now it's time again to let your emotions settle after these latest interactions. I am sure that you are thinking a lot about it- I know I would be! Remember to stay focused on you. And alwYs love yourself.
