Sounds pretty emotional to me.
I've never talked to a guy that didn't find asking a woman he loved and had been with for a while, to move cross country, as anything less than a big deal emotionally. Many worry about the relationship not working out and then feeling terribly guilty, not just because they're selfish jerks, but because they care. Because they feel selfish asking a woman they love but aren't ready to marry, to come be with them, when the truth is they really want to be with them.
Stop making assumptions. If you want to ask him if he's interested in marriage with you without bringing the baby into it at this time, OK.
Also, I think he has a right to know, though, before you make any more decisions including sitting on this or moving away. It takes two to make a baby, and you're not anymore entitled to the baby than he is. I support a woman's right to choose ultimately, but I don't think it's right to shut a man out of the conversation about it.
To say you love someone, and then get pregnant with their baby but not give them the chance to talk about it, or try to create the happy family scenario that you yourself seem to want as well, well, that doesn't sound like love to me.
