Confused

I have been seeing this guy for a few months and I really like him and we went on three dates and they went really well. On one of our dates he said he was going to move for 4 months to work in the snow so I thought this kind of sucks I’ve really started to like this guy and he seems to be interested in me cause he’s been on dates with me and people I know say that he seems interested else he wouldn’t make the time for me but all we do is snapchat and I really don’t know if he is interested in making this work cause he’s been acting distant for about a week and so I thought that we had stopped talking and I had come to terms with that but then he still snaps me and so I snap back and sometimes he doesn’t respond back so idk if he wants to keep talking with me or not.
