You know deep down inside, it's not working, instead of keeping that vow your mind is wondering elsewhere, why? It's because something is missing, you don't feel fulfilled, you must be tired of pretending. So why not leave your wife so she can find someone better than a Beta loser like you? She deserves much better. She deserves an alpha who can value her like a real husband should. Stop pretending and living a double life, come to your senses, leave, and let her find better than you.
