I suspect your man is one helluva lot wiser and more mature than you.
The wedding day does not reflect what the marriage will be like, just because your first wedding was shit, and marriage was shit, it does not mean that shit weddings equal shit marriages.
I really think you need to stop focusing on that big fab day that will be followed by a fab marriage. Any mature woman knows that the wedding day is just a day, a big stressful day. The important thing is the relationship, and the marriage. You wont get a fab marriage by sulking over the wedding. He does not want one. Respect that. But does he want the marriage?
You are coming across like a bit of a bridezilla wannabe to be frank, and perhaps too blunt for comfort.
You honestly dont need a "big day", read all the wedding threads here, it is nothing but angst and agony, not like the fairy tales you see in pink and fluffy american movies. And if you have been a guest at a fab wedding, you man not know the stress and strain that went on prior to this big fab painting of rosy marriage pictures.
Maybe your man will want to marry you, when he realized that being married to him is important to you, that committing to spending the rest of your life with him, is important to you. Not being princess for a day and center of attention in a big fluffy dream of silk.
Honestly, there should be "Bride Experience" parties for sale, along with Paintballing, Flight lessons and "Drive a Ferrari" experience days.
Good luck.
After thought:
The surname of your baby is the least of your worries, but in YOUR position, I would bow down, give the baby his name so he knows you are serious about him, and stop blackmailing him over that wedding day, using your baby and baby's name as a bargaining chip.
