How do you define love?
That is a hard one, there are so many types of love. The love you feel for a child, a friend, close family, a pet and that special love of a partner. Most of these take time to become love, the more you are exposed to someone the stronger your feeling will become. Sexual passion is not love, it is a chemical high your brain is on, if you stay with someone well past that chemical high and still like the way they make you feel about yourself, than you develop what most think of as love. Love of a partner is not unconditional, it can wain, diminish or even be lost forever. I feel that in long term relationships the ones that love are the ones that work past the lows, knowing that relationships have their highs and lows and do not just give up because they are in a low and do the work to get back to a high, now that is love.
It's different from "like".
It takes more time to develop.
it might be stronger than liking
Its' opposite is hate....the end of love is indifference....not hate.
Hate is when you've been let down by the alleged love/lover.
Indifference also takes more time to develop than hate.
