Does your husband always talk to your parents? My husband barely talk to my parent and i do not know why.

Maybe he feels uncomfortable in doing so? I'd definitely talk to him and ask him why, get his opinion and thoughts on it. If he doesn't feel comfortable, or feel like he can't connect with them, why not be the middleman and try to foster a relationship between them? Invite your parents around for dinner often, do things with them more often as well?
