Duke, hi! It's been a while...you seemed so good the last time you were here. I'm sorry to hear the girls are becoming alienated from you.
I can't help with W and L, other than to say I hope you have your own L to protect your interests?
Your girls are in an impossible spot. The only thing you can really do is be as positive as you can every time you get a chance to be with them. Do activities that help bond you as a family. Don't try and buy them - that is always bad for the kids in the long run. Things that are fun:
Bike Ride Picnic at a Park, Kite Flying Board Games Putt Putt Golf Movies - Even more fun if it's movie night at home - you can buy snacks, drinks, and settle in...set up pillows and blankets. Visits to State and National Parks
The more time you spend with them just doing things together, the closer you'll be. It sounds like W might be actively encouraging alienation? If so, please get them in to IC, document, document, and document - This is beyond harmful to them. They need a relationship with their father. Do I remember you saying your W's mother was the same way? You may need help with this. Fortunately, courts and society in general are taking this far more seriously than they used to. It's not funny, and it's not fair to the kids.
That's what I've got off the top of my head. Maybe some moms with kids your age can chime in, too, for more activity ideas. Shopping is always an option, but I hate that - the focus needs to be more on activity and less on material objects, unless they need something.
I'm really sorry, Duke. But, I am happy to hear from you!
