guy acts uninterested but says he is

So I’ve been talking to this dude for a couple weeks and well we would FaceTime and text and everything was fine and he said his family member was sick so he went to see them and he’s been dry as hell even after he got back from his trip should I just understand maybe he’s just needs space? leaving my snaps on delivered, his score is going up, but he’ll text my number?? I’m just confused should I block this man and move on or should I understand maybe he’s just slower at gaining feelings? been awhile since I’ve been in this dating game and I’m just kinda confused..
