Here is what you do:
Send her flowers at work. Women love flowers at work, It's proof to her coworkers that there is a person on earth that can stand her.
Go shopping for the items needed for the following advice.
Make her dinner with a quality bottle of wine.
Ask her about her day and mention that you think you would like her parents to move in with your guys when you guys start having kids.
Watch a nice romantic movie and kiss her lightly whenever they kiss in the movie.
Don't start fooling around! Tease her a little.
Walk her into the bedroom and tell her you want her to wear
This and make passionate love to you.
If she refuses and runs for her life, You had a good woman and the problem is you.
If she nails you, You should kick her out and have her brother move in.
