Put yourself in others' shoes. What do you think if your boyfriend likes a female star, such as Yang Mi or Zhao, and will spend a lot of money and energy on this female star, even more than you? If you understand your boyfriend's behavior, you will still be jealous and feel that your boyfriend doesn't love you enough. Presumably, many people feel that it is the latter, so it is not so strange that boyfriends are jealous because of idolization. Second, boys tend to be rational and want their girlfriends to be rational and idolized.
Why are most people in idolatry girls? It is precisely because women are relatively more emotional and men are relatively more rational. Differences in personality lead most people to worship emotional women. So when you like a star very much, your boyfriend may worry that you are too emotional and affect the feelings between two people, so it is not worth the candle. I might as well remind you as soon as possible to stop you. Third, as a boyfriend, I want to get more attention from my girlfriend.
A person's energy is limited. If you spend most of your energy on idolization, your time with your boyfriend will inevitably decrease. In this case, your boyfriend is of course dissatisfied, and you can't understand that you have to ignore yourself for an irrelevant person, so contradictions arise.
In short, idolization should be more rational. First of all, he should take care of his boyfriend's emotions. After all, it is a boyfriend, not a star, who gets along with him day and night. After getting the understanding of the other party, proper idolization is good for everyone.
