So Confused

Relationship Problems

Please help me understand. 3 years ago a guy came up to me and told me that my boyfirend was cheating on me and I did not deserve to be hurt like this. I left him and cried for 2 years. I finally got back on my feet but keep this person as a friend and had much respect for him and what he did for me, like a bit of my saviour. I put him in a special place in my heart. I also was very attracted to him but he was not available so I respected this.
This Dec we got together and he told me that it was over with his wife and that he was very unhappy with his relationship. We became closer and developed a love for each other so strong that I never thought I could love like this.
Our sex was so amazing and we would curl our toes together while we cuddle to fall asleep. WOW it was so amazing. The winter passed and I know he had to go to his home for the summer has he works as a guide and needed to go see his family. The kid is 2 years old, and his wife is depressive by manipulation.
OK so he leaves and we talk to each other on the phone. He was supposed to go see what the scoop was at home and try to see what he can do so we can be together. Last week end we met half way in a cute motel and spent the most amazing night and morning just holing each other and loving. We had breakfast the next morning and he said I'll see you at your house at dinner and I left.
Its been 5 days and he never called me and never came home. I find this so desrecpectful and I would not even do this to a friend. What went on in his head to change and not want to even call me? I am so confused. I know he did not have an accident and he is fine, working around the area for a few days.
I need to put closure to this as I feel so hurt Thank you
