I (28M) and my GF (27F) have been together for almost two years. My hometown is about 12 hours aways from where I work (that's where I met her and that's the place where I stay). I went to our hometown for Christmas and New Year celebration without her (it was always like this due to distance), but promised I will call her whenever I'm available. Our house consists of very small rooms and is very closed knit that any noise I would make might be heard. Yesterday, I was not able to call her that often due to family gathering and some trips with my mom but we managed to talk for some minutes. I told her I will call her later that night. I did call her around 9pm but she couldn't because she was also doing something so I waited for her. She only got available at around 10:30pm (during which, everyone at the house was already asleep). I went out of house just so we can talk with each other. When she observed that I'm outside, she didn't want to be in the call anymore and asked me to go inside and we continued to message each other.
She told me how much she's missing me and she's sad and that she wanted to talk to me a little longer. I feel bad for not having more time to talk with her, but I was fine if I talked with her outside of our house. She then told me to come to her, and to that, I told her that it is the only time of the year that I'm home. She then told me that we should not talk to each other anymore until I get to her and told me to enjoy my time with my family.
I'm not enjoying that I'm here anymore. I feel guilty for going home but at the same time, I'm not sorry (and should not be sorry) that I'm home. This also happened last year (where it was worst, because she would just straight up break up for not being able to call her), where I couldn't be on the call most of the time because of family trips and celebrations.
What am I doing wrong? And what should I tell her if I were to confront her?
TL;DR. Couldn't call my GF because of family celebrations that she doesn't want to talk to me anymore at all unless I get to her.
