It's only an issue if you treat her more/less favorably than other players. Treat her like a player while at the table, hit on her in your free time before/after the game.
Go for the girl... and pass off the reins of DMship to somebody else (not her) for awhile. You can probably just say "I need a break from DMing"... or "I want play for awhile".

If, however, your players look askance at you, there is another solution - institute a "the GM can be bribed!" policy. If they think you're giving special treatment to your girlfriend, fine, give them access to special treatment too, so it is fair.
