I was sad about something and I asked him for a hug and he opened his arms to give me a hug. While we were hugging, our bodies were completely touching. He had his arms around my upper back. A few seconds later, he pulled me in closer and held me tighter and moved his hands down to my waist. He placed his head over my shoulder and rested his chin by the back of my neck. Then he rested his chin over my shoulder while letting out a deep sigh. After he was done hugging me, he let go by slowly letting go of my waist. I'm friends with him and he's married. What does this hug mean?
