But I think what they are trying to show is the effect Anu has on Arya. Thru Anu, he is learning to live again, to love again - the carefree, happy part of him which has got buried under family duties and societal expectations, comes out with Anu
You got it right , his inner child finds his way out when he's with Anu.
I don't think we will get to see his 46 yr old side voh Anu k aane k bd se he has forgotten 
Office mein bhi he keeps playing dart game, mouse game etc etc just to please her 
Somewhere I feel he's insecure guy especially from his age pov ,he feels Anu will easily leave him for someone of her age usko koi bhi acha milega but Arya ko koi Anu ki age ka mile is rare thing hence he doubles up his efforts to behave like her age to make her more comfortable with him if he will behave like 46 bhaag jayegi voh
Bache k sath bache bnana padta h 
Like he told Jhende itne saalo se akela tha files k niche daba hua itne saalo bd meri life mein Anu aayi and sabko taklif hogyi
so he won't let her skip that easily chahe jo bhi Krna pde usko
