None of the Fallout: New Vegas expansions allow you to continue after you beat the game.
No, When you complete both Fallout 3 or Fallout New Vegas you are not able to free roam the wasteland.
Occasionally Fallout: New Vegas will freeze, but not as frequently as Fallout 3.

Fallout New Vegas is the fifth installment in the Fallout series. It is for the Xbox 360, PS3, and the PC.

No, you can't get married in Fallout: New vegas, but you can have sex in the game :)
fallout new Vegas will be on PlayStation 3 and Xbox 360
In my opinion, Fallout 2.
There are no drivable vehicles in Fallout New Vegas, unless added by a mod.
Fallout New Vegas is all one game.
