It didn’t take me long to learn that not only his sexual and sexualized activities but also his emotional, psychological and spiritual abuse tactics were the nuts and bolts of many disorders, including narcissistic personality disorder. But in the sex addiction treatment industry, the focus was always on his penis activities. Only recently have practitioners begun to name these other narcissistic tactics and sometimes call them “abusive”, and they’ve only done that because we won’t stop talking about it!
For all the time experts have spent trying to get a name that applies to wives and partners, they work hard to stay away from the name that applies to these men—abusers. Instead we hear that what these men do is “abusive”—as if that behavior can’t point to the name that so clearly applies—abuser. No, they may abuse wives, partners, children—ruining their physical health, their formation as human beings, their psychological health, their sense of safety in this world, their opportunities for education and financial security—but these men are sex addicts, not abusers. That way experts can avoid everything we know about working with victims of intimate partner violence and covert parental abuse.

No, you shouldn't stay with him to "work through it". You should not accept that while his behaviour is abusive, he is not an abuser. You should not nod along when your quite understandable PTSD is re-named Deceptive Sexual Trauma, and still not taken seriously.
You are a victim of narcissistic abuse. I don't recommend hanging around for the rebooted version, more abuse with additional bullshit.
