Boeddhisme
Love that clings is already suffering.
Buddhism makes a distinction that English blurs: between love as attachment and love as open-handed care. Attachment looks like love but is really a fear of loss wearing love's clothes. It clings. It is anxious. It insists the beloved must not change. Genuine metta — loving-kindness — wants the other's wellbeing whether or not they remain in your life. When you are holding on because you are afraid of who you will be without them, you are not loving them. You are using them as a painkiller. The question is not whether you still have feelings. The question is whether your feelings are clean.
“You can search the entire universe and not find anyone more deserving of love than yourself.”
