Try to not think of it as choosing between him or your family so much as choosing where you are going to live. It is a very difficult decision to make, and not one many can make lightly.
You are going to miss your family a lot at first. Desperately. Deeply, Some days it will be to the point where you wonder why you ever left. Then you look at this incredible person you love so much and you KNOW why, and it is worth it. Then one day, you will realize you miss them but love your new home area, new country, new life. It is more about starting a new chapter in your life, the chapter that starts the rest of your life together with your beloved. I missed my family a lot at first, then I realized that when we lived in the same state (hubby moved to the States before I moved to England), there would be weeks or even a couple months go by without seeing my family, although they were only 20 miles away. Between conflicting work schedules and life getting in the way, it wasn't always easy to get together, but we were able to phone or talk online. Being in England, the time was longer, but we still phoned and talked online. Now that we are back in the States, I miss hubby's family. A LOT.. but we have phone calls and Skype chats and keep in touch.
It is a big adjustment for you and for your family. Children grow up and leave the nest. Some just fly farther than others. It all works out as it is meant to be, and the initial goodbyes are the hardest. You cherish the time you have with visits and when you are in your new country, life keeps moving. Before you know it, it is time for another visit.
Big hugs to you, because I know this isn't easy.
