I searched through the sub a bit but only found a post from five years ago that a different user copied word for word and reposted a month ago so I figured a fresh discussion couldn't hurt.
Full disclosure and potential trigger warning but I am a spousal rape, domestic violence and attempted murder survivor so that may skew my viewpoint here.
First, Michael Michele and Blair Underwood put in absolutely stunning performances which makes this difficult episode easier to watch.
Now, the question: did Miles rape Valerie? Based on nothing but finding out she had a casual sexual relationship with someone, Olivia does a 180 and decides she was a liar. But why? Just because Valerie had consensual sex with someone doesn't mean Miles didn't rape her later. How many real victims are raped within hours of having sex with someone else? Miles was clearly angry and violent and lied multiple times during the investigation.
The ending makes it seem like we're supposed to think they're both bad people or at least both at fault, but only Miles illegally tracked the social worker's car. Only Miles violated a protective order and broke into her home. Only Miles committed assault. Only Miles lit his wife on fire and murdered her.
Yes, there is doubt because Valerie recanted but SVU detectives know how often rape victims recant out of fear. (I did.) It just seems so odd to me that Olivia said so decisively "Valerie wasn't raped" just because earlier she'd slept with someone else.
I'm still not sure, but given his history and later actions I'm inclined to believe he did.
