Just went through this
Last year, wife moved out after 20 yrs. No cheating on either side, no abuse, midlife crisis on her part, didnt want to be married any more. Moved out and moved across town. I kept the house and kids.
Did the twice a week dinner thing with the kids, and then in May, she's like, I'm moving to Florida. Got a joint attorney, split up the retirement money, no alimony, I agreed to fund the kids college, (I make a good bit more than she does) and we're done. Papers are filed. We're through.
The world's calmest, and possibly cheapest divorce. I always knew she wanted to go back to Florida, and there was no way in hell I was ever going back, so all in all not the worst thing in the world. Last three years had been a slow death as it was, not fighting, more like dual suffocation.
Taking a few months to get my teenagers settled with the idea, and then I'll start dating again, but to both of our credits we've kept it pretty amicable for the kids sake. May be wrong to think of it this way, but I'm the big winner in this, I kept my kids, who I adore, and she is gonna be in for a hellacious round of self inflicted guilt trips over the next few months when she realizes that she won't see them very often.
