Reject tutor's invitation to study in Australia

I really valued my mentor for asking me to study abroad. I finally refused. A short close-up articleArticle.

I have been studying for more than 20 years, from elementary school to middle school, from high school to university, and then to graduate school. The number of teachers I 've experienced is countless, but there are always a few good teachers at each stage, which makes me miss and touched. The most recent is Professor Li, my master's tutor.
During my study, I was the most memorable day during my studies. I missed the time when I discussed academic issues with my tutor, I miss my girlfriend's caring love for me during that time (now my fiancee) and my happy time to visit famous mountains and rivers with my classmates.
From the very beginning, my academic research capability was recognized by my mentor. He contacted me to study abroad and finally received a doctor from a famous Australian Engineering University, but I finally gave up. There are three reasons for giving up:
1. As long as I want to improve my abilities, I can get the opportunity to study there. I think I have prepared strong self-learning skills after my master's degree and have the confidence to explore various academic difficulties.
2. My family was worried too much. Some days ago, my elderly father was working in the farmland and his feet were bitten by a poisonous snake. I went home on a day and night to see it. There was nothing to worry about, if I had such an accident at home outside China, it would have killed me badly.
3. A person has been away for too long. I really want to have a home with my female friend early. I want to work or study hard and I will be more energetic.

The mentor is good. I rejected him, but he hasn't given up on my academic research career. He also said that he should work well at the company and pay more attention to the academic frontier, in the future, there will be opportunities for external exchanges and scholars. I should still be recommended. I really want to thank him. I don't want to disappoint him next time.
