I need advice. Something is happening in my home and I cannot continue to die in silence.

Two years ago, my Neighbour bought a 65 inches Television and my Wife said I should also buy a 65 inches Television. I bought it. 

A few months later, my Neighbour bought a Lexus Jeep for his Wife and my Wife insisted that I must buy her a Lexus Jeep too. I bought it.

As if that was not enough, my Neighbour changed his living room furniture last year and my Wife said she liked their new furniture and that I should also change our own. I changed them.

Two weeks ago, my Neighbour married a new Wife. Very beautiful young girl. But my wife has been acting as if she has not seen my Neighbour's new Wife.  

*One mind is telling me to inform my wife that our Neighbour has married a new Wife.*

It's been Two weeks and I have been waiting for my wife to tell me to get a second wife but she is just quiet as if she is not aware that my Neighbour married another Wife.

*Should I remind her?*
