Ignore your husband's cracks about "momma's boy". You are instilling the first very real bonds of trust, and that is SO important.
Here's a bit of my story, just to give you some perspective:
When I brought Kiba home, I had already planned to spend every available moment with him. I made a deal with him on his adoption day: You learn from me, with enthusiasm, and I will do all I can to teach you to be the best dog you can be.
I had decided I would likely have no sleep at first (a pup should go out for potty at least every twenty minutes, even in the night!). I decided he would eat the best food, and was willing to sacrifice a bit of diarrhea in order to change his diet from the crap-in-a-bag that he was eating at the breeders. And therein was our downfall. Unbeknownst to me, Kiba was infected with coccidia, a parasite found in well and pond water, and is usually no problem for an adult dog, but can cause a great deal of illness in an unprotected puppy. By the second week of diarrhea, my boy was very ill. I kept waiting for his digestive system to "kick in" and adapt to the new feed I was giving him! The vet took samples, and sure enough, it wasn't the feed giving him the runs, it was the parasite! ARGGGHHH!! By this time, he was dehydrated, thin, and pooping every ten minutes or more. His digestive system was in an uproar!
So, Kiba and spent the next three months together. Every second. He slept on my chest in my recliner chair, so I could whisk him outside for a fast, squirty poop when he needed to go. If I HAD to stand to do something, he was on a leash wrapped around my waist. He came in to the bathroom with me, he sat on my lap when I worked on the computer. He was WITH me. Did he follow me around even after he was well? Yup. Did he look to me for reassurance and approval while he learned a new task, or tried a new toy? Yep, yep. Did he follow me to the toilet for four years? Yeah, that too.
BUT! He loves my husband, even more than he loves me, and he had no problem making the transference. Dog's hearts are large enough to have lots of people in them, and although their families have a special place, your husband need not worry that he will become so enamoured of you that he won't make room in his heart for your husband!
To the immediate situation, your pup needs to be contained. He shouldn't have the chance to chew the wall, or anything else you don't want him to. There is no need for discipline, you just need to keep him safe. Whether that's with a line between you and him (I recommend that one) or an X-pen, baby gates or whatever. Remember though, he WILL get into stuff. That's his job. I mean that literally. IT'S HIS JOB TO GET INTO STUFF!! It's how he learns about the world. It's YOUR job to make sure all of his explorations are safe, for him and you and your belongings!
So, pick up your socks, hide the electrical cords, and fill your lap with dozens of toys, so you can stuff one after the other into his mouth when all he wants to do is EAT YOU!! The frozen wash cloth is BRILLIANT, and you'll want to keep a couple in the freezer all the time.
That give you something to think about, anyway. Good luck!
