Once, yes.
Being in love twice is normal.
I have been in love for three times, and there is a problem.
Fall in love four times, for comparison.
More than five times, I went to get married, which is a dangerous border.
Generally, it is not normal to fall in love for one or two months, and there will be problems in about half a year. More than a year has passed, I have experienced spring, summer, autumn and winter, and I have no plans or predictions for the coming year.
For about two years, I was basically running for my life and preparing for the future. Break up unless there is something wrong with either party. If you haven't been married for more than two years, four years and five years, it's basically because of the house problem.
So these time periods are listed for you. Look!
