Love is just a label that you attach to a human reaction.
In reality you respond uniquely to every moment.This response is dependent on your state of consciousness, means your awareness -- your intelligence, your accumulated past impressions, your worries your tensions your frustrations and your expectations from this moment.
As long as u understand this and realize its just a label, a utility that u call love, its fine.
Its for purpose of pointing to a unique feeling.
You dont love your wife ! or mother or brother or father. In reality you undergo all emotions , love, hate, detachment, sympathy with the same person at different instances of time.
While verbalizing, You just stitch these responses together and give it this name, Love. All of this is socially conditioned.
