I did not see that you tried to understand love in your post. But this my answer. hope it will help.
No one can understand love. The closet you can get to understand it, is when you become a parent and watch how your love take off on an auto and uncontrolled rocket traveling between the past, present and future, an between your mom/dad, wife/husband and your baby/children. I think you will get to realize that there is some manipulating power behind the veil that is trying to insure the continuation of life no matter what and whether you like it or not.
