Doug.
The needs for companionship and reciprocated love are just that.
Needs, not wants but needs.
Just like the needs to eat, drink, and sleep.
Its part of being human.
We all want to give up sometimes, I know I kinda do right now, but honestly then what would you have to look forward to in life?
With no one else to share it with all the recognition, good works, wealth, fame, or whatever you might possibly be able to garner just kind of seems hollow to me.
Who cares if you leave some kind of great legacy after your gone if you had no one to share the journey with?
You will find someone. Its difficult for us but it does happen if we at least try.
