It's normal. I opened the door to my wife's closet when she was gone and her robe was hanging on the inside of the door, I could smell her on it and I lost it bad.
He was cold because he knows he is responsible for hurting you, that's his issue to own not yours. The alone feeling becomes empowering after a while. You realize this is your journey alone to make. It was then I came up with my "I can handle it" mantra. Nobody else was going to do it. You have to take the steps on your own but you are not alone.
Cheers
