Abti, am not without empathy. With that said, there is maturity level people acquire and females are no exception. When you hit menopause, your views will be different and you will desire that your husband doesn't bother you with his constant needs.
The idea of getting old together sounds good but is unrealistic. It is better to live with reasonable expectations but not one that is based on dreams. You make wake-up from the dream and realize it was just a dream.
The point still stands. The idea of your woman being with another man? How does it feel?
Just reflect on that.
