Always bear in mind that you can never measure a love that is being given and a love that is received. Its two different things.
Nobody can compare love.
Like a fingerprint,each of us have our own intensity when it comes to loving. His intensity 10 might just look like intensity 5 to you but its already his all. it already counted his whole heart, but you chose not to care enough because for you, it did not even reached your standards of tru love - which is wrong, and definitely unfair.
