I don't think there's anything wrong with a married person of either sex observing and appreciating beauty in someone else. I think it's very wrong to follow (stalk?) someone when they are clearly ignoring you and they go inside their house. There's nothing wrong with watching porn.
There's nothing wrong with not buying his wife gifts - if she's happy to pick out her own gifts what they do is up to them. A man who quit his job does NOT make more money than his wife. He makes no money at all.
It's customary for married couples to support each other when one is looking for work.
It's wrong for him to follow other women around because that's harassment. I wouldn't quite class that as cheating, but harassing women like that would be reason enough for me to leave my boyfriend, and seriously confront and then potentially also leave my hypothetical husband. The flirting is a form of cheating.
I wouldn't call it serious or severe, but I would be annoyed by it. So, it is wrong. All of this, sans him turning heads, is wrong.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
