I hope you're able to find some peace with whatever you decide.
For me, I have a problem with finality, the finality of it all just means so much in my mind. If it's final, there is no more hope (at least in the same way) but it also means no more disappointment (in the same way.).
And to be honest, and I realize this is my sickness....I get scared he'll find someone else. Silly isn't it? EVEN if he stays the exact same, I get worried he'd find someone else.
Sometimes I think of some of my sick thoughts and laugh....I can't believe how diseased my mind has become.
