Need some help people?

Okay so i had this online friend and we talked a while back. We havent talked in 5 months and i finally got in touch with him. His phone got disconnected after 5 months and I couldnt find a way to call or anything. His mom treated me so nice the last time i was on his phone. Now he finally answered me threw facebook and he gave me his new number. I asked him to call me and he did. he said he would call back and he did. Then he started to forget to call me back. He always told me he had to do something. but the first time he did actually call me back. Now he told me over the internet that somebody stole his phone and he was robbed. Should I give him some space? Will he call me if I leave him alone?
