Tell him Good Luck for me. It's not easy moving to another place (trust me I'm in the middle of making that decision) but it's sometimes neccessary!

DH & I sort of just went through this very thing. He found this position in January. At the same time that I was pleased that he found a great position, I was also stressing about him being away from home. I am trying to be as supportive as I can but it's hard sometimes when I miss him so much. But oh well... this too shall pass.
