My dear , don't worry about the so-called love of this
material world. Just chant the Hare Krishna mantra begging Lord Sri Krishna to bless you with feelings of love for Him. When your love for Krishna awakens you will have perfect love for all living beings.
It is just like watering a tree. When you water the root of the tree all the
leaves and branches are nourished. When you give your love to Krishna you will be perfectly loving all living beings.
