So, he took the ow to see the movie. Now, that's funny. She'll have many ideas and what to do in the months to come if he strays or opts to call it quits.
The pocket knife has to symbolize something from his life if he keeps it on him at all times. A lot of this crisis people do things like that because it reminds them of a happier place in their "young" life. I just can't see the ow having one like his. What in the world would she need one for...to whittle away her free time? LOL!
Another one who doesn't know wtf he's doing w/a lawyer. The lawyers can spot them a mile away and know exactly what they are going to be dealing with. I'm sure your lawyer is just waiting to see what he and his lawyer come up with. He's not thinking about you or the kids right now...but he's most certainly think about how a divorce will impact his wallet.
I hope that you have been keeping record of things and have your financials in order so that your lawyer won't have any questions about spending, debt, etc. I know you already know this...but leave any of your documents out in view or somewhere he can get to them easily.
Hang in there.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
