My response:
Well, that's true. However, it's true for him also. Since he's been living in Texas for 1.5 years, he may no longer have any ties to the State of Virginia.
But, when it comes to divorce, jurisdiction goes to the State where one of the parties has filed. If, for example, the wife refuses to acknowledge Texas jurisdiction, that does not stop our writer from obtaining a valid, Texas, divorce.
However, if our writer has property to divide, or children, in the State of Virginia, then he'd better file in Virginia because not only are such items recognized as "significant continuing contact" with a State, but any other State would have no jurisdiction to deal with the child and / or property issues of the parties.
In essence, if there's property and / or children still in Virginia, then it would be a waste of time and money for our writer to file in Texas.
