Well when you've been through what I've been through (and I'm sure a lot of folks on here have), you get that nagging feeling the game is just rigged against you. That there are people you would be quite happy with and they with you, but some snake in the garden manages to ruin everything.
In short, I don't believe in this "wrong person" "all things work out in the end" kind of stuff. It doesn't. Some of us die alone. If I do, I will not die alone happily. That is a central pillar of my character and it won't change.
