Can Love Really not be Enough?

Dreams..God has used them to speak to His people in the past, and I don't doubt that He still can..and maybe does.

My boyfriend has had the same dream every night for awhile.  He sees me marrying another man..at first the face was known but changed a lot, not it's just blank..he thinks he may be someone we havent met yet. And he walks out of the church to people congratulating him on..something..he thinks building something, though perhaps not a physical type of building. Then a year or so later he sees me announcing im pregnant. He says the dream gets more vivid/detailed all the time, like it's almost as vivid as real life.

I'm..heartbroken. We're trying to pray and discern and be sure. I'd been unsure, started feeling renewed uncertainty, around when he started having the dream. It seems like an obvious sign..but the thing is, seeing how he's been so strong for me and how he's sought God through this..my uncertainty has died. I don't want to lose him. My questions about my desire to be married, to sacrifice for another, about him leading me. They're gone. And now I'm left feeling broken. I feel like God may be taking away my best friend just when I become sure I want to be with him, totally sure for the first time in our relationship. My love for him and desire to be with him have finally outweighed the pure fear of being alone. I don't think that I could ever love someone else like this. I don't want to just be married, I want him. I'm praying maybe this could be the purpose for the dream, but we're not convinced.

I've never been so sad for so long. Praying..just praying..
