Personally, I think ignoring her for a few days is the wrong choice- it sends a very bad signal to her that you might not want anything to do with her, and she may see that, get angry and follow suit. Honestly, I think the best policy is just to take it slow. Talk to her occassionaly as if you were talking normally- but don't do anything like kiss, sexual things at all to weaken that link so you just get used to talk as friends and nothing more- that should be kept up for weeks and you will be fine as friends I think
