When someone want's to be with you they'll be with you no matter what, even in life death situations(Family nhi manegi is biggest lie). And If they don't wanna be with you then even If you put your Severed head in front of them they'll leave for one or other reason. You care for them, and do each and everything to the perfection they'll leave. Mistakes don't end relations, its them they outgrew you. So don't chase anyone. Focus on yourself. Even if you leave everything for them, fight for them, sacrifice for them, they'll leave you behind crying and the person who wants to be with you will try to fix things, forgive you, understands everyone make mistakes, will accept your decision or will have a proper discussion even the issue take days they'll be there for you. Nobody leaves in one day, they have left you way before you know. Cause love is not something that you find in grocery stores that our vibe dosent match or whatever shit todays genration use as an excuse. Love is pure and its something you'll experience not something that can be explained. When you love someone even there name makes you gloom forget name even there city name makes you happy. Its like total bliss. Its not like you loved someone you left them now you are with someone else then next and next and finally settle on someone that is not love. That are just your hormones. When you love someone even if they leave you, hurt you, you still love them. Love is unconditional. You don't want anything from them just there presence is enough. So accept the fact and move on.

This is the biggest thing that youth needs to learn.
