The "Magical night" comment might have been just too much pressure from her to live up to. This is a woman looking for any excuse to end it, and also debating if you can change.
Please go back and reread your last 6-7 posts, you've made it all about her. All about pressure. What are your 180's, what are you doing for GAL.
Are you giving yourself and her enough space and time. I'm glad you realize the trip was a bad idea. That was putting a lot of pressure on yourself to pull off a perfect weekend. By your posts I could tell you aren't detached enough.....yet anyways.
Maybe you need to back up just a bit. Can u still go? Got a friend or brother/sister? I think it would be great if you could go have some fun yourself, for a few reasons. I hope you can figure something out.
