Why can't either you live in either place?
Mine was a little less, but I fell in love with someone over the internet who lived 200 miles away. Everyone around us said it would never work or last. And now we have been together a year and have been living together for 2 months.
Long distance relationships are pretty heart-breaking, but do work.
Would you be able to cope without seeing him for months at a time?
If there is no way of you being together then you'll just have to let it go, you can't spend your life seeing someone every couple of months for the rest of your life. As I'd imagine you'd want to settle down and have kids.
