Sex is only a tool in love, not love itself.

Do not seek for the best partner, but seek for the person who makes you a better version of yourself.

Let me tell you a story. There was a student who asked his teacher, what is love? The teacher said go into the field and bring me the most beautiful flower. The student returned with no flower at hand and said, “I found the most beautiful flower in the field but I didn't pick it up for I might find a better one, but when I returned to the place, it was gone.”
We always look for the best in life. When we finally see it, we take it for granted and after some time start expecting a better one, not knowing that it's the best for us.

True love is born out of the pyre of two committed souls.

Marriage is not a competition. Marriage is completion of two souls.

Try to respond to your partner instead of reacting.
