When we really care about someone, their happiness matters more to us than our own happiness, this is why Father God [1 John 4.8] sent Jesus to Calvary to save us [Matthew 28.5-6] and take us all back home, to Heaven. So Receive Jesus [Romans 10.9-10] .... God allows people in our lives for two reasons: either to be a blessing to us or to teach us lessons we are yet to learn, so in any case we won't be losing anything, by loving others [Matthew 19.19]
