I never stated that this was fact. It is merely an opinion shared by a number of people I know.
The quote was:
"Sexual dysfunction in a relationship is one of the main reasons for infidelity."
This certainly sounds like you're referencing a fact. Also, if it weren't intended to be taken as one, why did you say it would "take an hour" to find a source? That at least implies that it
can be sourced, which isn't something you'd say if you were just relaying the opinions of your friends.
It is not math. People are free to agree or disagree. I think this is why we are having this discussion to begin with.
We're having this discussion because you decided to imply that Trump wouldn't cheat because his wife is pretty.
To your best knowledge. What is the leading cause of infidelity?
Given how varied individual relationships are, it stands to reason that if you're going to try to group their failures into one category, that category's gonna have to be
really broad. So, if I had to make an educated guess based on what I've seen and heard, and think I know about human nature, I'd say it's usually a lack of appreciation from and/or general compatibility with one's partner.
Whether that's right or not, I'm pretty certain it's
not based on how attractive they are, since there are countless examples of people cheating on very attractive spouses.
