Affairs and Emotional Affairs Are different
Regular couples counseling is probably a bad idea.
I remember going to a therapist who didn't specialize in betrayal trauma and talking about emotional affairs. The therapist would paint my wife's reactions as unreasonable; they weren't. I was just gaslighting, and the therapist didn't have the tools to deal with it.
These emotional affairs eventually progressed into sexual infidelity. The therapist did no one any favors, and she wasn't wrong; she just wasn't equipped. She tried to stay neutral, and my wife needed to be protected. When infidelity is going on, professional resources really need specialized training; healing is very difficult without it. In some cases, it can do active damage.
When my wife and I started seeing therapists who specialized in betrayal trauma, we started to heal. Emotional affairs are betrayal; it is infidelity even if "nothing happened" -- something almost always happens, FYI -- and it breaks things in a very real, measurable way.
We just launched a professional directory at a cost to us, with resources that exclusively specialize in betrayal recovery.
