All realtionships end in pain, because there is always the sadness of separation, even if it is due to death.
Death is the end to everything. It's not an alternative, HisBrandy - it's not like you have a choice - !!

The secret is to secure an inner joy for yourself so that whether you have a relationship or not, your happiness does not depend on the inclusion of Love from someone else.
To hang your hopes of some happiness on the presence of a significant other, is to set yourself up for a tumble, sooner or later. Whether self-inflicted, or brought about by 'Life' tripping you up.

People hate it when I talk in this way. I get argument, some of it hostile, but it's down to a natural human resistance to accepting that whatever happiness we want and achieve in our lives, it is transitory. And so, by the way, is the cruddy stuff.
you have to treat the two, and accept them in the same way.

Hevk, you know, I wasn't born with this thinking. I had to learn it and accept it, too, but It's true.
I'm not saying you should do likewise, but I would ask you to burn an irrefutable argument in it, if you can.

And trust me, it actually isn't pessimistic, gloomy or negative.
