Where Did My Guardian Go?

I am new to this so bear with me. My family built a new house & I was the first one to stay the night in it (alone). I woke up to a dark figured man in the hall way outside my door. But he never left. I am 23 now and he has been with me ever since I was 13. My brother has even seen him walk down the hallway or from my room to the bathroom. I get a calm feeling from him and he no longer scares me. In the last year I had accepted my abilities more and have tried to open myself to these, in turn the man who has been with me has become stronger. Sometimes he is in the passengers seat and I turn and see him. I asked his name and told him I would like a better relationship. Minutes later a cold sensation touched the top of my shoulder and rubbed down my arms and squeezed my elbow like in a caring way. It was totally warm but that touch so freezing. He was always in different parts of my different rooms I have stayed in and almost watched over me while I sleep. I think he may help protect me or guide who comes to me. I recently moved and haven't seen him in my new house. It makes me worry. I haven't been without him before. I want to learn if I can contact him or talk to the others. Any help
