Welcome to catch-22

Oh crap !
Someone knocked at my door tonight with an envelope..., and yep, there it is, she beat me to the clock, she filed for D!

All of this because I told her I would ask for 50% of MY SON.
She has the nerve to ask for maintenance for her, on top of money for our son and wants 100% custody and allow me three visits per week. She must be dreaming! And yes LITB, I asked more time with my son and she refused, that is why I filed for 50% access, which, despite her D filing, I hopefully might obtain.
I SHOWED (acted) her my changes on top of promising them!

I realize I came across as faking my changes as a tactic, but no, I'm genuinely interested in my son, his well-being and his education. It's just that finances are not a problem, he's a toddler and until university time, there's a long way between.
We never talked about it before, because I was making enough money for everybody. As I said, I didn't see it coming. And after the bomb, she refuses going to counselling or M therapy.

I didn't buy myself anything excessive, and I buy toys for my son often for my -until now arranged- "visits".
As for my wife, I bought her several small things, a gift card, birthday gifts etc... but I didn't want to overkill neither.
(But yeah, I had to buy myself a car, winter boots, a new tv, a new computer, etc... I just arrived in the country!)

I think she has been talked into seeing a lawyer, and been convinced that happiness was found in D. I feel like sending her the first chapter of DR!

I've been there for my W consistently for the past 5 months, seeking reconciliation, seeking peace, being a perfect husband and father, and this is what I reap! Maybe yeah, she fears I haven't changed at all, but she should try me then!

And now, I don't know what face to show up with. "Oh how sweet of you for filing for D..." with a big smile, acting as if.
Or should I show myself not happy with it and tell her?
