Can someone please advice me if your husband is constantly 24/7 glued to their mobile phone without any communication or interactions and things are not the same as before. Even at night where he can not slp and just glued to his phone. It affect me badly. Nth resolved and this is getting out of hand, I Duno what to do anymore.

Maybe u do want to take a look together with him at what he is looking at, if he don't let you see, must be something wrong (i'm sorry to say that). If he is just scrolling fb, watching videos, talking to his friends, replying colleagues message, i believe it's ok to see together while he is using. And if really all this, have a talk, like "why not u go sleep with the phone outside and marry ur phone. Make love with ur phone etc." to tell him he over use the phone.
