I agree with Gnosis completely. Motorcycle class sounds awesome. I've ridden since I was 13. Have fun, and be safe.
I posted here in my threads about how I thought my W would never suck up her pride and ask for me back, but she did. She didn't do it with quite the "groveling" attitude I would have liked, ha, but she did it, and it's been all positive since.
Having children with someone is such a powerful bond, and it doesn't go away. I've seen that this whole DBing effort is really an effort to diminish the WAS's confidence in their decisions. It's a two pronged approach, one to make yourself a better, more interesting person, and two, to let them feel your loss. As long as they have that gut feel that they could come back whenever they want to, they have NO real reason to take that scary leap back toward you. Remember, the leap away from you was very scary to them too, and they won't take the return trip until they feel they have no other choice.
As time goes by, as they live their life, as their fantasy about whatever OP is in the picture starts to fade and die, and as they see you moving on without them, they will feel that pull. The more completely and convincingly you do your part, the stronger that pull will be. If deep down they are still bonded to you, because of history, because of kids, because of their belief in marriage, that pull may eventually convince them to make that jump back.
When I was a kid we had a cat. She was a grumpy old thing, loved to go outside, but only when the weather was nice. I'd open the door for her in the morning, and she'd stand there in the doorway feeling the air, trying to decide if the freedom was worth whatever cold, or rain, or wind she felt. She sit and sit, taking her sweet time. We learned that if you slowly started to close the door, little by little, she'd see it closing, and at the last second make that bolt to the outside. Nine out of ten times she'd opt to go outside rather than be cooped up inside. Lesson is, not until she knew her time was almost up would she force herself to take that gamble. There's a reason women are considered the "feline" gender!
