Well its been a few days since then. I would reccommend calling her today or tomorrow and inviting her to tag along with something you are already doing this weekend with friends if possible. Something like, "I'm going to the mall with friends on Sat, you want to tag along?" or "I'm going to return some Christmas gifts, you want to tag along?" Already have a purpose for going out. Make sure the purpose isn't her, you are a busy social guy, she's lucky to hang out with you.

Keep it short and sweet, about 5 minutes on the phone. When you get her on the date go back to building comfort with your DHV routines and such. Remember the game is played in comfort.
