Talk about being an open book.

Although polyamorous relationships aren’t as taboo as they once were — one couple revealed the dynamics of their open relationship that has people scratching their heads.

Fernanda Fabian, a relationship coach and host of the Polycurious podcast, revealed that she and her boyfriend, Michael, have an agreement where she is allowed to go out and date other people — while he stays at home.

The couple agreed on this eye-raising setup early on in their relationship, and it seems to work for them, despite some jealous feelings in the beginning.

While it works for the duo now — there were moments in the early stages where Fabian felt guilty about exploring other connections.

“When I started having feelings for other people at first, I felt like I was doing something wrong,” she told NeedToKnow.

“These didn’t impact how I felt about Michael – if anything, I became more appreciative of him. Now, I only feel guilty if I feel like I’ve compromised my relationship for someone else.”

Fabian said it’s taken time for the two of them to feel comfortable with their openness.

“He doesn’t experience jealousy anymore because he feels secure in our connection.”

Fabian also explained how she makes it a point to show her love and gratitude for her boyfriend.

“Even though he doesn’t ask for it, I constantly express my love and appreciation for him. And I always try to put our relationship first.”

The couple does have some boundaries. “Whenever I go on a date now, we don’t talk about it. Unless I’m struggling with something and need his support,” she told the outlet.

Although Fabian goes out and has her fun — Michael isn’t as keen on following suit.

“A part of me wants him to have that experience because I know how fulfilling it can be and in some ways, even addictive to our relationship,” she expressed.

“I’m pretty sure I would experience some jealousy, though. But those feelings would eventually go – just like they did with him,” she said.

This couple isn’t the only one that thinks fooling around with others is a good thing — another duo believes that becoming swingers saved their relationship.

Jem Jones and her partner Daz started having their fun with other people five years into their “ethical non-monogamy” relationship.

“People class it as cheating and say we are ‘splitting marriages up,'” said Jones.

“People are angry about something they don’t understand. We’re having the best time in our 40s.”
