What happened to Huang Rong after middle age? Why can't you accept it?

Huang Rong should be the most complete one among so many goddesses in Jin Yong's martial arts novels. From a queer girl to a middle-aged lady who is a mother, it is very grounded and has a real change. Some changes are hard to accept, mainly because she is too suspicious of Yang Guo's attitude and disapproves of Yang Guo being with Little Dragon, so the audience thinks she is a little petty and stingy, which is hard to accept. How did she become like this?

First of all, she has great doubts about Yang Guo. However, this suspicion is human nature. Yang Guo, after all, didn't grow up around them, and he didn't know his behavior, so he wondered if he would go bad. Yang Guo's father is Yang Kang, and there is such a lost relationship between Yang Kang's death and Guo Jing. Therefore, Huang Rong was afraid that Yang Guo would take Guo Jing as his father's nemesis and deliberately take revenge on them, so she would doubt Yang Guo and not teach him martial arts, in order to protect Guo Jing and the people around her. After all, Yang Kang is really bad. She is worried that Yang Guo will learn badly outside and follow in Yang Kang's footsteps. Personally, I think Huang Rong's suspicion is understandable. They are all human beings, not so selfless.

Secondly, Yang Guo worshipped the little dragon girl as a teacher in the ancient tomb, but Yang Guo wanted to marry the little dragon girl, that is, the master, which was unacceptable in Huang Rong's eyes. In ancient times, people paid great attention to respecting teachers and attaching importance to Taoism, and disciples and masters were together. In their view, this is a very perverse thing and they are not ashamed of Jianghu people. Therefore, it is understandable that she prevented Yang Guo from being with Little Dragon Girl. After all, it's for Yang Guo and Little Dragon Girl, and I don't want to embarrass Jianghu people. However, all these behaviors are very annoying to the audience. I feel that two people obviously love each other, and they are a good match, and it doesn't interfere with Huang Rong. Why did Huang Rong come out and stick a thick stick, which made middle-aged Huangrong less likable?

Finally, anyway, I think Huang Rong's behavior is beyond reproach. If you were in her shoes, you would do the same.
