Oh dear... I honestly cannot imagine not having physical intimacy anymore in a marriage, or even only 1-2 times per year! I understand how intimacy can wane in a marriage after a while. But my opinion is that if you are not physically attracted to her anymore and there is zero intimacy, what's the point of therapy and of staying together? It honestly sounds like it's pretty much over. A marriage in my opinion is not just to co-exist in a house together. A marriage should involve attraction and intimacy. In therapy, you'll only discover that it cannot work anymore. Sounds like you're ready for something else. And if you're walking on eggshells? That must mean you're not addressing the elephant in the room. No sex, no attraction..... I would skip on the therapy and think about separation. That's just my own opinion of course!
