What force keeps you bonded to samsara?
The force that keeps one bonded to samsara is desire. Desire for continued existence. 

"Even in the midst of utmost Dukkha, why doesn't the realization come that let me leave this path that causes Dukkha altogether"   

Because, most likely, you only intellectually realize Dukkha and unless you are enlightened , you have the habit of wanting to continue your apparent existence.

Many words, like "ignorance" are not exact and precise translations from the original Pali words. A better meaning of ignorance (in a Buddhist context) is what one doesn't deeply understand. If one only has an intellectual understanding of things like  dukkha, impermanence and not-self then one is still ignorant in the heart of those things.

People mix love and attatchment. This is just what is. It is possible to love without attatchment.

Maybe I am missing something somewhere but what does  our ability to love one another have to do with what keeps us bonded to samsara?
