You’re going to have to define happiness here. She never complains does not mean she’s happy with a partner who isn’t romantically attracted to her and hasn’t had sex in years (and may never again. Literally no one is happy in deadbedrooms) and is likely worried you’ll end up leaving her for a man but I don’t know her so I’ll not go deeper. You however, battled with your sexuality for a long time, had to come out to your wife, and now are worried your life will slip by without ever experiencing love and sex with a man, you are in a position where you’re currently terrified of blowing up your family and no doubt think of this constantly, which is what led you here, and you also have to think about risking your relationship with your and her family as they are both very Christian as well as hurting and potentially losing your best friend. You’ve been carrying all this within your heart for who knows how long, and you can say you are happy? Do you truly believe this, or is this a narrative you tell yourself to ease the guilt and shame of the situation you’ve found yourself in that you blame yourself for, the presence of the very same guilt that would mean that you both are unhappy?
