To worry that I’ll be cheated on

[Heygal]

I am newly married to my husband after being with him for 9 years. I met him when I was 19.
He personally is very principled and has always been adamant that a relationship is about trust and he would never cheat. I do want to believe him 100% as that is within his character. This isn’t something I bring up with him as I respect him and he’s done nothing for me to suspect infidelity.

The only problem is almost every man that I know and what we see in media; be it fiction or non-fiction is that cheating almost seems inevitable? My own father and brother have cheated as well as many other family members for example. Whilst I am sure not that every single man has cheated or would cheat, it feels sometimes that it’s a when not and if.

AIBU and I’m feeding into the media stereotypes and portraying men into a bad light?
YANBU to have my wits about me and think the chances are it will happen?

I think YABU.
Cheating partners make good story lines in fiction (where's the story in happily married for X years?). Ditto magazine stories.
I know very few men that have cheated (DH included, married 30 years). That said, I don't think there's anything wrong with being mindful that it could happen, but thinking it's inevitable is a tad dramatic. Will be interested in other opinions, though.

YABU to ever conflate truth with fiction.
However you clearly have trust issues from your father/brother. Have you thought of therapy?

You don't hear about the men who don't cheat.

So many couples just get on with their lives without cheating, but nobody ever heard about that.

I've been surrounded in my life by men who didn't cheat (that anybody was aware of) and strong partnerships/relationships, so my experience of men cheating, differs from yours.
