'My Fair Wedding' Host David Tutera -- Dumping My Husband ... and We're Preggo with Twins


"My Fair Wedding" host David Tutera is breaking up with his "husband" after a 10-year "marriage" ... and a war is brewing over the couple's unborn children ... TMZ has learned.

So why all the "quotes?"

Tutera and his longtime partner Ryan Jurica had a big wedding ceremony in Vermont back in 2003 ... but since they live in California (where gay marriage is not recognized) they filed for a domestic partnership.

But now, the relationship is OVER ... at least according to legal docs filed by David, seeking to end the domestic partnership because of "irreconcilable differences."

Here's the twist -- according to the docs, filed in L.A. County Superior Court, a surrogate is set to give birth to TWINS for the couple ... and she's due in July.

David wants full legal and physical custody of the kids ... and only wants to give Ryan visitation.

He also doesn't want to pay a nickel in spousal support, but wants Ryan to foot the bill for all legal fees related to the split.
