Buddhists say I won't have a real marriage until the second half of next year. Should I refuse if I show up now?

Of course you can't refuse. Happiness depends on your own hands. I have never heard of anyone who can get happiness through "waiting" and "fortune telling". Don't waste your time waiting for nothing, and stay away from happiness.

Scientists believe that people have "free will". Then, human behavior is also free. Happiness is the cumulative result of various intentional or unintentional behaviors, and it is impossible to have a definite result at the beginning.

People should believe that they can change their lives, and don't be superstitious about the fate of heaven.
