Advice

So I am dating with my boyfriend for 8 months and we are always together usually but now Christmas he wants to go back to his country to be with his family. He said he will stay with me but now when I said I like his family and how much he cares about them he said he might go. And I want this too, the problem is that it is extremely hard for me. It feels like there is a hole in my heart. I know it sounds so selfish but I don’t want him to go. At the same time I want him to go because this is important. I just want to do the right thing because he deserves the best. I just don’t know how would I be okay several days without him.
