Long distance

Hey guys. So my situation is kind of different. Two years ago I met this guy while travelling in Australia and immediately hit it off. We did long distance for a bit over a year with only seeing him a couple weeks during that time. Last April I moved from Canada to Australia to live with him for a year. Although I love him, I have never been fully happy here. I’m constantly missing home and my family and some mornings I just wake up and cry. I got to go home over Christmas and see my family and having to leave after that was so hard. I head back home in April and he plans to move over in a year, so that’s another year or so of long distance. Then the plan will be to stay in Canada for a few years. But he wants to know if I will be able to live in Australia again in the future... and right now I just can’t see myself being so far away from my family ever. I’m so torn because I love him but my family always comes first to me and this is one of the hardest decisions. I didn’t include every detail so feel free to ask if I missed something. Any advice or insight?
