Hello Eric,
Thank you for your honesty and the level of openness you expressed in your post. I think other readers may benefit from your experience as well. We are certainly finding ourselves in ever-changing and more diverse situations as career practitioners today.
I am happy to see that you gave your client the best support possible as you would any of your other Military Spouse clients and that you were comfortable enough to express and share your feelings with them as well in a non-judgmental and respectful way. It might have not come off as genuine if they saw your initial surprised reaction and then if it wasn't addressed. Kudos to you for being honest and willing to share with them. There were many lessons learned here and it sounds like you will be even more prepared for unique situations in the future!
