不是所有爱都是情不是所有情都是爱
[bù shì suŏ yŏu ài dōu shì qíng bù shì suŏ yŏu qíng dōu shì ài]
Not all forms of love lead to romance, and not all romances turn out as true love. The person might be pointing out that while there's an immense depth to feelings, not every kind is the same and sometimes romantic relationships don't develop into true, enduring partnerships despite initial signs of affection.
