Woman who was the ‘unicorn’ in a couple’s existing relationship dishes all the details – from how they hid their throuple arrangement to why it ended

A woman who was the 'unicorn' in a couple's existing relationship has revealed all the details – from how they hid their arrangement to why it ended.

The anonymous user, believed to be based in the US, took to Reddit to reveal that she was dating her best friend and her husband.

She told people online they could “ask anything” about the polyamorous arrangement, which lasted “more than a year.”

Social media users rushed to the comments section and posed their questions for the woman in the popular thread titled 'Ask Me Anything'.

The message read: 'I was the 'unicorn' in a marriage…

'Basically what the title says. I was in a relationship with my best friend and her husband. Ask me anything.'

According to Okay CupidA unicorn in a relationship is “when a couple invites someone else to join them as a third romantic partner.”

'The connection can be for one night, or it can be a long-term arrangement that all three enjoy.'

After being asked about her experiences and how things started, the woman began to reveal her secrets.

She said: 'We were drinking and smoking one night and joking about it. Nothing happened and the next few days were quite uncomfortable as many people think they want something when they are in a certain state.

'A few days later she came to talk to me and said she meant it, she wants a third. Then, a few months later, the time had come. We set boundaries and rules and I was with her without him at first just to test the waters.

'He joined gradually, after which it became a full-fledged relationship.' She added that while it was a little weird at first, it quickly became “amazing.”

Another user then took the opportunity to ask how she felt “comfortable” with the married couple.

The couple added: “The first thing was making sure her feelings were validated. Making sure she never felt like I wanted him anymore, and if she did, we would talk and see how I could reassure her that I wouldn't interfere with their relationship.

'This could stop at any moment. She did the same for me. If I ever didn't want to be with him anymore, I was done for. If I ever wanted to end this whole relationship, it was fun while it lasted.

“It took a while, but it honestly worked out well and they are still happily married and we are still friends!”

The “unicorn” went on to share that the “sex” was the best part of the relationship, adding that she also appreciated the trust and communication the three of them had.

She noted that the relationship did indeed take place outside the bedroom – and said she and the man often went on fishing dates together while she and the woman got their nails done together.

The Reddit user explained that they hid their relationship from the couple's children before opening up about how it ended.

She explained that the relationship had ended on good terms – adding that she had decided she wanted her own children so knew she had to walk away.

'It was a clean break. It ended because I found myself wanting my own children. I loved (and still do) her children and wanted that for myself and knew that wasn't feasible in that situation.

“It would be too weird to have his kid in my opinion, lol. I don't think I would be friends with him in the future. I don't see that I benefit from confiding in another man who is not my husband, and although I have male friends it is different with him because he is someone I would feel comfortable with , because he already knows my history.

'That's just asking for trouble and I don't want to flirt with a statement that could hurt my husband or his wife.

'I think a conversation about it would help, but it doesn't always go according to plan. It just would have been easier to set the boundaries already for when it's over.

“Like if it's okay for us to still talk, hang out, etc., or if that part of our relationship is gone. “I didn't want to bring it up afterwards because I didn't want to stir things up and make her wonder why I decided to end it, but still want to be emotionally present with her husband, you know?” she explained.
