According to Zen Master Thich Nhat Hanh, "true love" has four elements:
Loving kindness: this produces a lot of joy and happiness.
Compassion: it makes us and the other people suffer less.
Joy: "If love does not generate joy, it is not [true] love."
Inclusiveness: "In true love there is no frontier between the one who loves and the one who is loved."
I'd like to focus on "compassion" here. Don't people who are more compassionate suffer more because they experience the suffering of other people in some sense? So aren't the elements 2 and 3 as mentioned above contrary to each other?
I think this question is related but not identical to another question asked before: love and caring is suffering.
