New Here - long distance marriage

Hubby and I have been together for 13 years, married 7, we have 2 kids, 5 and 2. He has been in a different state for 3 months for work. I stayed behind with the kids so the 5 year old could finish preschool. In 3 more months we are supposed to move where he is to be reunited as a family. But I'm having second thoughts. There are no obvious problems in our marriage. No abuse or infidelity. But I'm just not happy. I feel like I am going through the motions. When we video chat I find we have little to talk about. So obviously adding a cross country move into the mix will only cause more stress. But if I say I'm not moving then our family will be torn across the country. We can't do counseling as we are hours apart. I know I need to tell him how I feel (he will be blindsided), but it seems like a crummy conversation to have over email or video chat. He came back for a few days and I found it more disruptive and stressful, than exciting. I know that isn't a good sign. But I don't know what to say. I know he will want to bend over backwards to make me happy, but I don't know what I need. I just know I need more. But asking for "more" seems like an unfair request to make of him. I don't know what advice I am seeking here. I think I just needed a place to write out my thoughts as I can't talk to him easily. I have only just opened the "divorce" door in my mind so I'm trying to feel out my options. Thanks for reading
