What reason has she got to lie to her best friend? She wants to file for divorce, quite clear that.
You're missing the point. You're right - she wants to file for divorce right now. But that doesn't MATTER.
She is running on pure emotion right now. She's working off of her feelings. But feelings can change. Are you always happy? Tired? Hungry? Cold? So just because she feels something today doesn't mean she will feel the same tomorrow or the next day or the next week or the next month, etc.
The point is that in order to potentially reconcile with her, you need to look inwards and work on you. Let go of your fear and your need for control. She's going to do whatever she's going to do. The only chance she turns around is if you are the Kyle that she'd be a fool to leave.
Kyle it's funny that it seems your either not reading what others are writing or you don't believe it. You say your more at peace... Do you think that's a feeling? Do you think feelings change? Go back and read what darkness wrote (what I quoted)...
The only thing you can control is what you do, look inwards and start fixing what you think should be improved. You said earlier your not a spiritual person, may I suggest that you work on that. Go to church, or meditation, or something that will help you look into yourself, I think you would find it very helpful.
