Please help! It seems my wife is addicted to lesbian porn.

From a male blog reader.
Good day! dvicxy, I read about your last post about a man whose wife wants 5 years gap between their children, I would love to narrate my own story maybe I will get some help from here. I will make sure my story is as short as possible and I will appreciate you posting it very fast.
I am mike by name ( false name) I got married in 2013 after dating my wife for complete 3 years, she was then a very submissive wife; She use to love what I love and never question my decisions over anything including our sexual acts. I remembered I was the one that introduced her into anal sex and she never complained but instead will tell me she is pleased with anything am please with. This her submissiveness  made me to step up our relationship and turned it into marriage .
We have so far been bless with a 1 year old baby, some months after my wife gave birth she became a new person, a very strange person to me. She will shout at me and speak abusive words at me anytime we have just a   simple misunderstanding. The worst part of it is her love for lesbians porn. I never introduced porn to her before not to talk of lesbians porn, but this day she love lesbians porn more than even Nollywood movies, and she recently act detached from me anytime we are having sex, no more I love you from her. She will just serve my food on the dinning without even telling me food is ready. Every time I sleep with her is like am sleeping with  a wood, no more passion from her again, As am writing this am sure she has added masturbation to her habits.This is creating a lot of fear in me;  I fear she will one day leave me and the baby and hook up with a lesbian partner.
Please help me should I report her to her parent?
