I am 34. I am married. I still remember most girls that I met either in school, college, tuition, or in the playground. Some I could talk to and some I couldn't even gather the courage to talk. There is a very strong energy in these feelings Nikhil. You live for that energy. You need that energy with you to live life. The girl left but she lives rent-free in your heart. You will meet many more girls like that. Ultimately whoever God has chosen for you will be with you till the end.
