Neeluravi,
Let me put my 2cents here.
Most of the couples face the same problem(?)
Guys even when they are considered chatterboxes to outsiders talk less with their spouses.
Reason from a guy's perspective:They are more interested in cosying up with wife than waste time talking to her

Only time a guy speaks a lot is while going on a long drive .Try it if you want your guy to talk endlessly

Hope i haven't offended you with my suggestions.
