Jessica, I am sorry this hasd happened to you.
I went through something similar, but it ended poorly.
Communications is paramount, so please, please keep that open. I am VERY glad to hear that your spouse will be seeking counseling, as that is important in understanding, clarifying, and processing the transition for both of you. I am happy to read that she is willing to be supportive, a very good thing.
I know this will be a difficult period to get through, and I do wish you all of the best.
Michelle
