masterly,
"..but also realize there is no way they could ever understand.."
Yes when telling friends and family about my then wife having a gay affair it was hard for them to wrap their heads around it...just as it was for me... it was a horrible thing that no one has experience with ...except folks on this board.. That said, it was still helpful to get support from friends, family...build a support system for YOU. I have no experience with couples counseling but for the that therapist to say "tell no one" indicates that the therapist is trying to repair and maintain the relationship and be what? your sole means of support? If you feel you need more support I urge you to get your own therapist, psychiatrist, priest, rabbit, doctor, etc. It takes an army of support when dealing with this.
