Our close family friend who I have a crush on is distancing himself from me?

Our family friend (31 M) and i have been hanging out a lot especially everysunday. At ome point i lived with him for months and we ended up getting super close and i think that is when i fell in love with him. Anyways two days back we were hanging out and he told me he will be moving states in few months and that made my heart sink to my stomach. Anyways after that he seems kind of distant over the phone like he normally speaks to me for a while and we chat but he seems like guarded in a way and it hurt me. Any Men out there who might give me an insight to what he is thinking or maybe i did something wrong? Should i distance myself the next few months as well?
