I don't know if you decided to be together because of deep love or other reasons. In fact, love is different from reality. You see, there are contradictions now. As for what you said, she didn't agree. I know very well that my girlfriend is in Shenzhen and her personality belongs to the south. It won't be so good for him to come to me, so I don't want him to come, but I hope he can come. I think your girlfriend should be as contradictory as me.
Your problem is still lack of communication. The biggest problem separating the two places is distance. Some words are beyond our words and deeds, so we lose some warmth. Moreover, they are really bored at work and the salesmen are very tired. You should be considerate of her, don't think for yourself. You can discuss anything that bothers you with her.
As for academic qualifications, I personally think there is still a gap. I don't know how different you are, but it is more important for a girl to have a kind and sincere heart than education.
Communication is the most important thing, understand?
