Congrats, sir!
Treat her right and you'll love marriage.
Also, getting her trained about the Skins ahead of time is great. My wife hated football when we got married, now she sits with me during games, even replays of preseason games I DVR'd and asks questions...trying to learn the game! She surprised me with a trip to Fan Appreciation Day last year. They can be trained if you just saturate them with all Redskins all the time. Wives are tougher than kids to indoctrinate but if they really love you, it can be done. If you catch one who doesn't have a dedication to a team, at least.
