My opinion, definitely with someone else.
It's the only reason I haven't CTB yet.
I do not want to die alone as I've lived for the last decade struggling with my issues in solitude and silence.
For me trusting someone, feeling something for a person I grow to care about and them, me, one more time is worth it.
The process can be painful, been trying for awhile now.
I've met some very beautiful souls on SaSu trying, now it gets harder and harder as friendships develop and then go away again as others I now call friends CTB.
No matter what you plan with someone else, it can always change at the last minute or not happen at all over small things or large even if there is a connection made.
You end up with a friend you have to watch suffer or die before you go and vice-versa.
I have a few now, and one who I would actually continue to live for, doesn't fix anything wrong with either of us or change the path though, particularly painful.
Just have to cowboy the fuck up, wipe the tears away and start again.
This is the second time on site for me under a new name after deleting my account when an accord had been struck.
No matter how sound the plan made is or how committed you become to another, no one knows exactly how they will react till their finger is on the trigger so to speak.
When it falls apart you can't get angry or turn your back on them.
You have to respect the choice made, continue to support each other, and decide to go alone or keep trying with someone else from scratch yet once again.
As I have said in my partner post, "a relationship based on death is a very different animal than one based on living"
