If your partner has many people they flirt/sext with, how do you handle it?

I know I have nothing to “handle” per se besides my own insecurities, but was curious about how open partnered/married NM couples communicate regarding this.

Do they share every new person they talk to with you? Do you only want to know if they have new sexual partners?

I’m trying to navigate this. For me, I was pretty much thrown into this lifestyle. My husband cheated, has been to therapy, but hasn’t stopped flirting or talking to MANY new women. So he says he wants an open relationship. It wasn’t my ideal, but in order to stay together, I’m trying to navigate the heavy flirting.

Unfortunately, If I happen to see his phone screen, I get a visceral response. Like nauseous and fight or fight kicks in immediately. So he hides this from me. Which also feels bad.

I think I’m reacting to this just like I did when I found out he was cheating. It’s a continued trauma response.

So, in asking about navigating your partners flirting/new people or interests, I’m trying to get a feel for how much information is good to have, or what the general consensus is about sharing in relationships.
