if u really love someone with ur deepest point u feel this way
Love is not about spending time together or marry each other or seeing each other every day. Love is about selfless care.  if u can do something for someone selfless.if u care for someone without expecting that they should also care for u.
If u can cry for someone if they are in pain .without let them knowing.
If u feel happiness for someone if they feel happy.
 Love  happens between souls not between 2 bodys.
U dont need someone physically next to u.
As shree kishna said 
If u love someone set them free cuz freedom is the most loveable thing to living creatures 
If u understand this congratulations u are a rare soul.❤️✨ प्रीत
