choose the right path so you will be happy :D
like i said you are the bus driver of your own life journey
some ppl might board the bus
some ppl might alight
you will never know who will board and alight next
if this person wants to alight at this stop
you can't stop him
unless he is willing to stay abroad
so just let him go
because you will never know who will get up next
