We feel your word is misused, as Love is a spectrum, not all-encompassing.
Love = wholeness*
The eventual flaws leading to adversarial relationships instead of healthy progressive relationships are as follows:
1. Insisting on marriage to complete relationship. In fact, marriage negates each person's free will in many ways (socially, personally, legally)
2. Believing another will complete us and make us whole, when in fact there is a reason people have referred to "falling in love" as "giving your heart away". This is not healthy.
3. Romantic love unbalances our lives. Romantic love gives away the benefits of whatever balance we had created prior to the romantic connection.
Compassionate love enriches the balance we already have. Compassionate love allows us to share the benefits of the balance we have created without losing this balance. Compassionate love is sustainable.
If romantic love were allowed and expected to be temporary, we could go to this "romantic love" vacation and expect to come back to home base (the balanced life we created prior).
