There are often couples who have to be separated due to work - medical residents, academics, etc. Your job,, as OldUser says, is to document your trips to visit each other. Keep ALL airline tickets, bus tickets, receipts for gas, hotels, if applicable, plus records of how often you speak to each other online or on the phone.
It is not insurmountable. It's just a little different. Also document your time with the relatives who are supportive of you.
Best of luck on your journey!!!
