It's GREAT to hear from you - both the good news you've had in your personal life, and the love reflected in your story.
It was a lovely chapter. I could feel the emotions - from the nightmare of angst during the car ride to his mom's immediate sadness - part from her son being gay, but moreso, probably from the thought of him probably never coming to know the ultimate joy of sharing a new life made by you and your life's love. Children are a force within a nurturing soul that cannot be adequately described - without a reference point, it's something you can't fully comprehend.
My oldest is 24, yet I can still remember the feelings, seeing him for the first time as he entered the world, as I cut the cord, knowing that he was the union of my love for my wife and hers for me.
That is what I am sure his mom was feeling.
I know they want the best for him - for him to be happy - and that is coming through in his father's gentle guidance.
Then, the relief of the stress, and the passion - certainly an arousing (lol) Climax - or would that be denouement? to the chapter.
Thank you for sharing both your real and your "fictitious" life with us.
I'm glad you have a good support structure out there in the real world.
We all need one - our orientation doesn't matter - just BEING matters.
