He's not talking to her because he's got nothing to say. He wants to fuck and he's pissed Pretty obvious.
If I had to guess, I'd say he's a pretty horny guy, loves his wife and wants to fuck her , and she would rather watch fucking television.
Seriously talking, his feelings are hurt and he thinks his wife doesn't love him anymore. She's not fucking anyone, she's just not a passionate person. Passionate people make fucking the priority
Being pissed and ignoring your wife is definitely not going to make things better.
There's a saying that arguing with women somehow you always loose, he's probably avoiding her by thinking out his future.
In this case she's refusing him time after time and playing "DUMB" that somehow rejecting 25/28 times is normal. She knows
something isn't right, then posting this on reddit to somehow gain support and that her actions where "right" from the beginning.
Yes he is immature and bitter, but only because she made him that way.
