Sorry to hear about what happened. Sometimes stuff like will happen. No two people are alike which means at some point, one will upset the other. The question is - how is it dealt with. Sometimes space is needed for awhile. It's only been a few days. Give her a week or two, send a message after that. If she has cut you out of her life, I agree, it hurts and hurts bad. Only one thing you can do at that point - use it as a learning experience for future friendships.

If she comes back around, use it as a learning experience for this and all friendships. Everything in life helps us grow. Life is about constant learning and change. Sometimes it hurts. Allow it to grow you stronger though when at all possible.
