I met this amazing girl a few weeks ago. She is everything i could ever hope for. We had this amazing connection right from the start and its well umm amazing

When i asked her to go out of town with me for the weekend she got very anxious and just kept telling me she didn't know. It finally clicked tonight in my head tonight that i have been going about this all wrong. I took it as her being closed off and depressed. After hearing her increasingly grow more anxious over the thought of making this plan it all made sense. I refuse to let my ignorance to this disorder ruin the potential of our relationship. I have been doing some reading but i thought it would be best to get some opinions from others.
I need to know the best way to approach her about spending time with me. I hate that i caused her an anxiety attack. It is very important to me to learn how to handle this in the best way possible. Any help you all could share would be very much appreciated.
