Anyone's hubby acting like a kid??

Jessica • 29 years old, in love, and married. Mommy to Lucy born in March 2016. I am complete.
Help!! I think my husband is reverting back to a child. It seems to get worse and worse as my due date approaches. He's picked up bad habits that he dropped years ago. He seems uninterested and generally lazy. He's constantly playing video games and wants to spend all his time with his guy friends. Everything I ask of him he does the opposite. 
What's the deal? One last "hurrah" before our baby comes or is he just not who I thought he was? :-/
