It is that time of the year again; love is in the air as Valentine's Day approaches, even in the DC Universe. Like in the real world, there are relationships that are great and those that are dysfunctional, at best. For those relationships that exemplify the best of the best, there are many common factors that are the same, but some do the relationship thing just a little bit better than others.

While every relationship is different and can change over time, the ones that remain strong do so largely in part because the two care and respect the other. If anything, some couples in the DCU become stronger when faced with adversity, while others still have a lot to learn.
