I’m really sorry you’re going through this. Ten years without intimacy, especially without open communication, has to be incredibly tough. It’s not just about sex, but feeling wanted and connected.
Vaginismus is real, but if your wife isn’t willing to address it or talk about how it affects both of you, that puts you in a painful spot. Your frustration and loneliness make total sense.
Before making any major decisions like a hall pass or affair, maybe consider therapy, either for yourself or as a couple. You deserve to be heard and supported, too.
Wishing you clarity and strength.
