I think you've mistaken directness for lack of care. What @Ragdoll Circus means by building a narrative is that you've told yourself the "story" of what happened in such a way as to point to abuse. It's there in the language you use, which elicits an emotional rather than a rational/cognitive response and the way you describe it in the third person. A good example of your use of language is in the part I quoted before. While I might question the wisdom of bringing guys back to the house for sex when you've got tiny children, the kids were sleeping, she had sex, the guys left to take you home, the kids were sleeping and knew nothing about it.You guys need to ease up
Using emotive language about the woman's acceptable behaviour (having sex while her children were sleeping - isn't that when most parents have sex) takes people to a place where they think "if she would do that terrible thing what else is she capable of", when she hasn't actually done a terrible thing. The other part of that is that consensual sex with an adult, threesomes, one night stands, whatever kind of sex it was, doesn't equal someone then being capable of rape or sexual assault, which you point to with your use of language (e.g. The idea that stopping at a cemetery with a young person in the car means something sinister rather that it generally being the one place you'll be able to stop on a country road).
People telling their actual trauma history generally don't need to use language to bring out a reaction in the reader, the reaction comes because the story was so awful. And putting yourself in the third person makes it much harder to connect with what you've written. It sounds like you were scared, being taken to a remote house to look after kids you don't know for someone you don't know is all kinds of scary in and of itself. Filling in the gaps isn't helpful though, when it takes you to a place of searching for something that may really not have happened.
It's clear you have actual trauma to deal with and that's what I'd be working on. Are you still living at home with your parents? Parental substance misuse is horrible and can lead to really neglectful abusive parenting, and you have a rape that you are aware of. Work on those issues and, if there's anything else to remember, it'll come in time.
