With the Respect for Marriage Act though, if a couple is married in one state, they receive the same rights if they live in a different state.
The infuriating thing about the Respect for Marriage Act is that it shouldn't even be necessary, thanks to the full faith and credit clause which essentially compels one state to recognize legal proceedings in another state. Which, to be fair, has only been around for 225 years and therefore may have slipped through the cracks as it was published in a little-read journal known as the Constitution of the United States of America.
