here is a major swoon idea. if you can pull this off, cause I don't know enough details.
cook a romantic dinner, or learn to cook her fave meal.
Set the table with some candles and some flower. NOT roses. to cliche. Blind fold her if you want and lead her into the room with the dinner.
All romance doesn't need to be going out. Just cuddling and watching tv or a movie is always nice.
And if you want to up the anti. Play a game. cards, board, whatever. Make bets..."who ever wins this round gets a free back rub, a favor of their choice, etc" it can end up getting interesting
just some ideas. hope they help.
