You've just started the conversation. It is only the beginning. Keep talking about it. Don't nag, but be persistent. Tell her how you feel, but try not to be pathetic. Your not asking for the moon, just some love. If you stand on your own two feet and tell her the honest truth without backing down, you might not get laid but you will earn her respect, not to mention your self respect, which is actually a good start.
Moving down the hall is actually something I am considering for my own situation as a last resort. Sort of a "house separation." Maybe you shouldn't do this yet. It doesn't sound to me like you have exhausted all of your resources.
Good luck,
Tony
