The greater your capacity to love, the greater your capacity to feel the pain, meaning when you love something so much, the higher your chances of enduring every difficulty that comes with it.
We humans can develop a strong feeling towards something we admire a lot. However, the more the feeling towards something gets stronger, the more we do not want to do away with it. Love is a beautiful thing in life, and almost everyone gets to experience it. Although, some people end up not having to love anybody or anything because of the horrible and heartbreaking experience it caused them. Not everybody may realize this; the more you love, the higher your chances of disappointment. Let's say, for instance, in a relationship, before you get to date someone, you, first of all, develop a crush before it transcends to love. Now, the more you keep on loving that person, the more you always realize you want to be around them. However, no one is perfect, but you might one day get disappointed, especially if your partner is not sincere with you or cheats on you.
Always know that loving someone or something comes with a lot of conditions. Pain is unavoidable no matter how cautious you are in life. Therefore learn to control the way you love in order not to feel so much pain when you get disappointed.
