Background. Career beta, married shortly after high school. Married 10 years, 3 kids. Scrawny my whole life. Discovered MRP after wife started hanging out with neighbor all the time, under the guise of our kids are friends with his kids.

Been unplugging for 4 months, lifting and trying to STFU. Early success followed by my slipping back to beta or near enough and it started again. So, today I let it slip that I was invited out after work. She's clearly upset asking who asked me. I STFU and ignore her. Eventually she gets to me and I give up names, two girls and a guy. She's pissed. Asks more and I change the subject, telling her it doesn't matter and that I didn't go so it doesn't matter. It's clear this upsets her but she drops it for the time being

I have a feeling this is not over. How can I best handle this later when she starts asking again? Thanks.
