Have a Friend going through this and the topic came up in another conversation.
In Texas, the requiremnts of Common Law Marrage are:
1. Both parties agree they are married
2. They present themselves to the general public as married
3. They live together
Without all three, there is no common law marrage
In reguard to #3, while you can be considered Common Law married after a single day living together, the state requires you live together at least 2 years before either party gain any rights
And if you meet the requiremnts for Common Law Marrage, you have to get a divorce to end the marrage, just like any other marrage
