What is true love?

I learned that we stay with Who we should and not the one we would like. sometimes the person we should be with. makes so much sacrifice we don’t even appreciate and we hurt. We remain in hypocrisy, there is a search for an impossible love. Even having someone around who deserves our attention and affection. Some people do not seem to tire of being rejected, the more ignored the more obsessed they become and without realizing it hurt their own heart. And we think that no one else deserves our love, we reject the opportunity to be happy for an unrequited love.
