You feel a lot of love for someone and they do not take it. What do you do?
Turn the love into hatred and wish for revenge
Again and again remind them how much you love them and how little they love you
Become fussy and cranky
Feel humiliated and try to protect your respect
Resolve never to love again
Feel hurt and mistreated
Try to be aloof and indifferent
...and you have seen that none of these work. They only make the situation worse.
What is the way out of this? How do you maintain your lovingness?
Have patience and change your expression of love.
Be centered and limit your expression of love. Sometimes over-expression of love puts people off.
Take it for granted that they love you too and accept their style of expression. For example, a mother with three kids. One child talks, one child does not talk, one child throws tantrums. Mother's love is the same irrespective of their behavior.
Genuinely acknowledge their love for you. This will turn your demand into gratefulness and the more you are grateful in life, the more love comes your way.
Know that hurt is part of love and take responsibility for it. When you move away from your center, you will definitely get hurt and the nature of worldliness is misery.
