Friend got divorced. Here is the farewell letter he wrote to his ex-wife:

Emotions are never forced; meeting is already a lucky sign. I shouldn't obsess over feelings that aren't mine. Only now do I realize that until the day reaches its end, you don't know who will stay with you till the very end. Sometimes, when you meet someone, you think she is the one, but in fact, I am just a passing guest in your life.

That day, I thought we would meet again, so I didn't say a proper goodbye. Please allow me to once again state the meaning of my appearance in your life.
If one day, when the whole world abandons you, I hope you remember that there was someone in your life who loved you sincerely and passionately. I hope that love can give you courage and help you get through difficult times.
I have never regretted loving you—then, now, and always. My eyes have never been mistaken about people, and I still believe so. Meeting you is the luckiest thing I have experienced in my life.

From now on, you must find someone who is truly suitable for you. The most suitable person for you is not the one you love but cannot have, but the one who understands your temper, still cares nothing, and is willing to stay and accompany you.
He must be someone who won't leave you easily. Deep feelings are not as important as long companionship; love that is genuine needs no words. Every relationship requires mutual tolerance; if both parties lower their heads alternately, they won't drift apart.
There are no naturally perfect matches—only one who understands tolerance and concession, and another who knows when to stop.

At that time, don't be moved by a stranger's kindness and take the complete dedication of close ones for granted.
In fact, only the warmth and concern of family, the daily companionship of a loved one, and the silent support of friends are truly important. You need to have a balanced perspective. Those who value you as a person rather than the value you can provide are the ones worth spending your life with.

Also, don't speak sarcastically to loved ones, don't ignore them, and don't speak angry words. Don't hold grudges against them, and avoid silent treatment or cold wars.

Later, you should also regard "not being afraid of losing" as your confidence, holding it tightly in your heart. In this life, we ultimately live for ourselves. Whether it's a good friend from the past or someone you deeply loved, once the relationship is broken, don't cling to it anymore. Remember, loss is never a one-person matter. If the other person doesn't care about losing you, there's no need to hold on stubbornly.
You are already enough—kind and good. Missing you is his loss, not your regret. Don't be sad or anxious about it anymore; don't doubt yourself. Just step away with dignity and decisiveness.

In the days to come, get close to those who make you relax, make friends with sincere and reliable partners, follow excellent people to improve yourself, and strive to become a better self. Let those who missed you regret it slowly.

I will still believe in love, but I no longer hope that love will come to me again. If I miss it, so be it.
I have seen the darkest darkness in this world, but I will not fall into it; I will always grow toward the light.
The bravest person in this world is not the one who has never seen darkness, but the one who, after experiencing storms and rain, still chooses to step on shadows. However, you might not witness this process.

All principles are in books, but how to be a person is outside the books. From now on, I want to live well for myself. Keep going.

Finally, I hope that the next time you shed tears, it will be because of happiness. After bitterness comes sweetness; there is always a time to wait for flowers to bloom in the sun. Words are too limited to express, and I pray your prosperity surpasses spring. Crimson rain swirls into waves at will; green mountains transform into bridges intentionally. Half of my pure heart is simple and plain; the other half quietly seeks happiness. I leave old matters behind, and next year I will still welcome blossoms.

There is gain, there is loss; loss, there is gain. Do not chase after gains, do not grieve over losses. Let gains and losses follow fate, keep your heart unchanged, go along with nature, and follow what your heart desires.

Let it be so—when the pear blossoms fall, the moon will set in the west.
