For those who opened a long-term monogamous marriage, what tends to feel safer and work better early on: your partner having one regular, known person they see, or keeping things more open to new people?

I can see arguments both ways. A regular person might feel more predictable, but could also create stronger emotional attachment. New people might reduce that risk, but could feel more uncertain and harder to manage.

What has been more common or healthier in your experience, especially for the spouse who is adjusting to their partner dating first?

I posted here the other day about my wife and I starting to explore opening our marriage.

Since then, things have become a bit more real. She has been talking to a guy and is now talking about possibly going out with him in a couple of weeks.

She isn’t pressuring me and we’ve agreed honesty, check-ins, no secrecy, marriage/family first, and that either of us can pause things if needed.

But I’d be lying if I said I wasn’t struggling with the reality of it. The idea of her getting ready, going out with another man, flirting, connecting, and potentially wanting more afterwards is bringing up a lot of anxiety.

For those who started from a long-term monogamous marriage, how did you handle the first actual date?

What boundaries mattered most before it happened?

Did you want updates during the date, or is that a bad idea?

And how do you tell the difference between normal jealousy/insecurity and your gut saying this might not be right for you?

A few months ago I posted here about how my wife had suddenly become more confident, affectionate and adventurous after a long stretch where our relationship had felt emotionally and physically distant.

At the time, when she first brought up opening the relationship, I honestly felt blindsided. Part of me felt hopeful because we were reconnecting again, but another part of me immediately felt insecure and scared about what it actually meant.

Fast forward a lot of late night conversations, honesty, awkwardness and soul searching later… and we’ve agreed to cautiously explore non monogamy together.

For context, we’re married, have kids, own a home together, the whole “built a life together” thing. This is not coming from hatred or wanting to leave the marriage. If anything, we probably communicate more openly now than we have in years.

What’s strange for me emotionally is that this shift seems to have come alongside a huge increase in her confidence.
She’s always been more reserved and understated, but lately she seems genuinely happier in herself. More playful, more self assured, more comfortable in her own skin. She’s naturally very attractive, slim, blonde, dresses more confidently now, and I’ve definitely noticed more attention from other people when we’m out together. We went to a wedding recently and I remember looking at her thinking she looked genuinely happy and glowing in a way I hadn’t seen for a long time.

And honestly… part of me loves seeing that version of her.
But another part of me feels intimidated by it too.
If I’m being completely honest, this is more something she wants to explore than me. I’m not against it in principle and I’m trying to approach it with an open mind, but I’m definitely the more anxious and cautious one out of the two of us.

One minute I feel excited by the honesty and openness between us. The next minute I feel physically sick imagining her connecting with somebody else. I swing between thinking this could be growth for us as a couple and wondering if I’m slowly agreeing to something that could emotionally destroy me.

The thing that makes this harder is she genuinely isn’t pressuring me. She’s actually been patient, reassuring and understanding throughout all of this, which somehow makes it feel even more real.

We’ve agreed:
complete honesty
no secrecy
regular check ins
family and marriage come first
either person can pause everything immediately
no rushing into anything physical while we process emotions first

I think my biggest fear is this:
How do you tell the difference between normal jealousy/insecurity that you work through… versus your gut telling you monogamy is fundamentally what you need?

I’d really appreciate advice from people who started from a long term monogamous marriage and later moved into ENM/open relationship territory.

What mistakes did you make early on?

What boundaries ended up mattering far more than you expected?

And did the fear eventually settle down… or was it trying to tell you something important from the start?
