Relationships are much about give-and-take. Base it on love, build it with faith and there's much for both to compromise. If both can't reach that stage, the relationship is bound to crumble. Though there are times when the passion dies down, and the feeling wears out and both get tired of each other, if there's even love in the first place, it's really not that hard to rekindle the waning flame. It just takes a bit of effort, and time.
