Have I made the wrong decision?

I told Frank that we couldn't move in together and gave him my reasons for it, ie, his divorce not being finallized. He's moving 40 minutes away. He lives right behind me and has to move his stuff 40 minutes away? We've had such a good last few days. Today we were out and he told me "I'm moving 40 minutes away and I don't know what will happen with us in the future." I'm about to cry right now. He's coming over in a little while to use my car. Who have I made this decision for? Myself? God? My sisters? Other people who may look down on me for it? I think I've sealed the fate of our relationship. When he's gone I'll never forgive myself for it.
