Moving away

My husband and I have been talking about moving to Nevada for a while now. Yesterday he told me that his friends brother owns his own company out there so he has a set job and that brother will also help us find a house. I feel like everything is moving along now. It was all talk and now that it’s happening I don’t know how to feel. Both our families are here. He’s not close to his but I am and I don’t know. I feel happy and want the best for my two girls but I feel like I’ll start feeling home sick and depressed.
