The most comfortable relationship is not necessarily between spouses,

But it must be a soulmate.
What is a soulmate?
Love you, but not to make things difficult for you,
I understand you and will not hurt you.
Give without asking anything in return.
You're tired, and he feels sorry for you.
You cry, he comforts you.
I love you, but I won't cling to you,
I miss you, but I won't cling to you.
Those who like you care about your heart.
With a heart of trust, do not restrict the freedom of others,
Cherish your freedom and do not abuse it.
Accompany like family,
Talk heart to heart like friends.
No deception, no concealment,
No scheming, no worries.
I understand your unspoken words, and you understand my hesitation.
Everything has an explanation, and every matter has a response.
Don't worry about bothering each other,
Don't worry about being unnecessary,
Cherish each other when you meet happily.

If you are fortunate enough to meet such a person, you must cherish them well. A good partner will become a light in your life, illuminating the path ahead.
