I sympathize with your feeling of not able to find love.
Life is love. There is no way you can be content in life without love. Money, house, expensive vehicles, gold etc all become of no use if you are using it alone. The satisfaction we get is when the person we love admires our hard work and efforts to get all of these materials for them. That is emotional satisfaction and love.
I find it hard to believe you are not able to find love. Love is everywhere. It can be found in the heart of all humans and animals alike. I think the problem here is you are not able to convince someone to love you!!!
What you need to understand in this case is , you are unable to accept rejection and this is not love. Being adamant and being loveless are two different things. People always mistake convincing and forcing someone to love them, is true love. No it is not, and even if you are able to convince them, Love will not last longer.
If someone is not interested to Love you, accept it and move on in life. Only when you move on is when you will be able to find love, or else you will be stuck in the shell of rejection and never get out of it. Try and understand that there are 7.6 billion humans out there in the world, and this is not the only person alive to find love.
You will eventually learn your lesson and get love, provided you are willing to entertain new love in your life. Or else Love will keep knocking on your doors, but you will be giving it a blind eye, because you are looking for love where you will never find it.
