My g/f and I did not have anything planned for Friday night so I thought I would suprise her by taking her to a hot spring and spending the night there and take her for a sleigh ride in the morning at a ski resort. It was a spontaneous thing I wanted to do before I started my new work schedule next week.
Anyways, when she called me that night, I asked her what the plan was? She said that she was going to dinner with some friends for a going away party (the third one). When I got to her home, she said that it was a last minute thing and didn't apologize for leaving me with nothing to do. She said that she wanted me to hang out with her for an hour before she left. At this point, I was irritated and wanted to leave so I didn't say something that I would have regretted. She asked me what I was doing and I said that "well I was going to take you to the hotsprings" and she said that her friend was leaving and nothing else. I did not mention to her that I had a room and a suprise for her (sleigh ride) that night.
So half an hour passes and I become even more irritated and I said "im gonna take off". She said that she would like me to stay so I stayed. While I was stitting on the couch, she asked me a couple of times "you dont have to stay if you dont want" so that drove me nuts and I upped and left without giving her a hug/kiss but said have a goodnight.
I didn't go to her home early like I do on Sats but stopped by latter on in the day because I was still angry with her. She wasn't home and I called her, but she did not answer and I left a message in the afternoon.
Fastforward to today when I went over to her home to apologize for my behavior and tried to talk things over. She didn't let me into her home, so I stood at the front door trying to apologize to her for my actions. She was still angry with me and said that she didn't want to talk things over at that time. The conversation wasn't getting anywhere so I said "well I will give you your mailbox key back" (only key) cause when she gets mad, she doesn't talk to me for a while. I also said that "i wont bother you anymore and I will give you your space". Then I left.
Do you think that she might have misunderstood me for wanting to break up with her for giving her key back? And did I mess up our relationship by walking out on her? Any response would be appreciated.
