We have dealt with this same issue for almost 15 years. My husband and I are from two different states. I was raised here, family is here. We have moved back and forth between the two states more times than I'd like to mention. We've also lived other places. No matter where we lived, my wonderful husband has always moved us back here when the homesick was too much. The last time we came back, it stuck. We finally decided to grow roots, mainly for our kids. We've ever been happier. I'm so glad we did!
I can't really offer advice, because everyone is different. But I do understand the feeling and the situation. I hope you guys can figure out the best solution.
