And this is one of the reasons so many men never know. After suffering thr trauma of a sexual assault, no one wants to have to deal with emotionally carrying yet another man who can't control himself and them clean up the mess of his self absorption after.
So you just keep to yourself. At least then you can maybe process what happened to you in peace without the added financial difficulties of a family member/boyfriend being in jail, on trial, potentially losing his job, etc.
That shit is about them, not you; and it hinders your further.
