Momiji-sama
This is a humble answer to the question.
Sometimes “romance” can blind people, and various adverse effects may occur.
From the basic law of Buddhism that everything is empty, there is nothing that can be viewed as a reality, but as ordinary people, we are caught by ignorance, and it is unavoidable to some extent that we become obsessed with various things and things. However, it is hoped that various afflictions and attendant afflictions occur due to reality views and obsessions, and misconduct will accumulate due to that act, and as a result, receiving rewards for bad karma ahead of time will be avoided as much as possible.
However, I think it would be terrible to suddenly “let them eliminate ignorance, worry, and bad work.” It may be effective for those who express the Bodhi Heart and have practiced the three sciences of precepts, determination, and wisdom to some extent, but it's not easy for us who are ordinary people.
Now, it comes down to how ordinary people should respond, but in the case of Momiji, an emotion that has become passionate due to “romance,” it is an “uneasy” heart, but how to first suppress that heart and whether or not you can return to yourself where you can make calm and normal judgments is important. “Romance” is an instinct, so we must make adjustments so that we can firmly return our reason, assuming that it is difficult to suppress it from our head.
That boyfriend needs to think carefully and calmly about his future, such as whether he is seriously thinking about his future, for example, whether he is seriously thinking about marriage, children, life plans, etc. for the future, whether this relationship is causing trouble to people around him, such as family, friends, work, etc., and whether it is a relationship that is positive for both of us.
After thinking calmly, if this love affair (in Momiji's case, due to “anxiety” feelings, etc.) interferes with your family, work, or life, I know that it is important to leave once, as Inoue Hiroboshi said. I pray for Momiji's happiness.
