How do you make a long distance marriage work?

I have been with my husband for a year, we recently got married in July…. I live in San Diego and he lives in Henderson, NV. Neither one of us can relocate right now. My 15 year old son is stable i high school here. When he graduated the plan is for me to move there. My husband owns his business and cannot move… We love each other and spend just about every other weekend together. Sometimes he is able to come here for a few extra days at a time. Anyone else in a marriage like this? Any encouragement? I do have an active life, for the most part, but I miss him so much… any advise?
