Especially if you don't get married later, whether it's a boy or a girl, what you can't get is always special to human beings.
There is no pressure in the university environment, and the love at this time will of course be unforgettable. But you left school, stepped into society, and started a family. You have a responsibility you can't get rid of, a career you like or can't bear, and an unspeakable pressure. Even if you are satisfied now, you will never be as broad as you were in college.
It's like human beings always yearn for a golden childhood, just like plants have phototaxis, and everyone yearns for beauty and purity.
However, you said yourself that you are happy now, and that is the most important thing.
You can recall the past, but you'd better not dwell on it. The past cannot be traced!
Also, do you know that you talk in your sleep when you dream? If you take the initiative to tell your husband about it, that is a situation; But if you are heard by the other person in your dream, it is disrespectful and even harmful to him.
Never let your past hurt your future.
Even if your college boyfriend is terminally ill or still loves you, what are you going to do with him now? Can you cure him of his illness? Your husband doesn't love you? The important thing is, do you still love him? Love enough to think that he abandoned his happy life now?
Personally, I don't have such a situation, because first of all, I seldom dream. Second, the past is not so beautiful that I cannot forget it. If so, then I will turn it into the present, not just a useless memory.
