My wife and I are exploring dating couples but unsure how to navigate different interests

My wife and I have been ENM ever since meeting each other 6 years ago but only ever played independently. We’re now exploring playing together with other couples but this is a totally new dynamic and aren’t sure how to handle certain situations properly.

I recently matched with a woman on a dating app with a partner. I was interested in playing with her independently but she suggested meeting up with our partners. My wife was interested enough in her partner to see where things go.

We’ve hung out with them several times, we really enjoy their company and they’re great people. However, my wife doesn’t feel the chemistry between herself and the other guy. I am still interested in exploring things independently with this couple if they are open to that.

Now my question is, how do we best communicate this with this couple? It feels weird and bad to basically tell them that 1 half of us is not interested in them (my wife would probably still be friends with them though). We have a group chat with the couple where we’ve done all of our communication since the girl introduced the idea of us exploring as couples. Do we just be blunt and transparent in the group chat? Would that be uncomfortable for either of them since it’s a let down in front of others? Should I avoid mentioning my continued interest? We’re really struggling to navigate this as it’s our first time exploring as a couple.

Any advice would be much appreciated.
