My wife and myself are mid 50's and it's getting rough trying to continue this marriage. One child - college grad with a minor in Psychology - has labeled her as covert narcissist. Either way, she has cluster B traits.

For years she seemed to over-react (lose her temper) to things that most people wouldn't react as strongly to. This seems to be a form of "intermittent explosive disorder" where the reaction is disproportionate to the trigger. In the past decade it's gotten worse.

Likewise, for years she also seemed to have "suspicions" that I'm unfaithful, whereas anyone who knows me knows I have zero flirtitious behavior. In the past decade this has grown pretty much to "pathological jealousy" (Othello syndrome) proportions where she's certain I'm having an affair on the side and constantly is checking my phone or anything else for clues. I'm not on social media of any kind, but she swears I have a secret account somewhere. Stuff like that.

Lastly, this mostly happens (episodes) after about 6pm, often escalating throughout the evening, sometime to the point where she'll be quasi-raging past midnight. Once this "episode" behavior starts, I know it won't stop until she eventually falls asleep. And yes, wine in the evening often fuels this (I don't drink, but she does)

I'm at my wits end with this, and it can't continue. Is there anyone else out there dealing with psyche traits similar to these? What's your experience? What is the best course of action, especially considering that she does NOT want to seek counseling or help?

We live in PA which is a no fault state, and we only have one child left who will turn 18 in about a year.
