It’s written with many tones of denial, hesitancy and almost fear to it, as if written by someone who really was in super-denial (and sounds like an abuse victim, tbh). Like she doesn’t come out and say she caught them in the act. She doesn’t even say she heard them. (Could a troll resist this?) She also doesn’t…

‘he hates quickies because they ‘feel dirty’

*shuddering*

Don’t feed it; it won’t leave.

First I was like:

HOLE EE SHIT.

You don’t let crazy Indoors.

Tip:

If he’s so worried about his sister’s neck why doesn’t HE sleep on the couch?

I prefer Queerty’s version of this, where they keep me updated on the latest reddit tales of straight guys having gay sex. More succinct and plausible.

If you have to set up a nanny cam to catch your fiancé having sex with his sister it might be time to peace out. Just saying.

Right! I feel that whether or not they’re having sex doesn’t matter. He’s treating her terribly and that’s enough reason to leave.

I can’t imagine how anyone would put up with that shit for a week much less 4 months. This cannot possibly be a real story unless the poster has the lowest self esteem of anyone ever.

when the very best scenario is that your future husband and his codependent sister are inconsiderate assholes it is time to get out.

If this is real then they are either incesting or all-but-incesting. This is not normal brother-sister behaviour. Normal brother-sister behaviour is when my bro and I go in for a hug but we’re really both trying to out-manoeuvre each other to land the first punch to the other’s upper arm. Not this nonsense.

You know things are bad when you reach the end of the story thinking the sister with the crack addition and hand tattoos and an aversion to showing and working is the “good” one.

Wouldn’t that be DTSFA?

There are enough red flags to say time to run.

You left out the part where he wanted to take his sister on their honeymoon.

If this isn’t just a piece of creative writing, her hisband’s relationship is at best extremely unhealthy. At worst.....it's Game of Thrones levels of unhealthy.
