White Knight Rescues

You could swoop in on your horse, or modest Japanese compact, and save her before she is exposed to irreparable psychological damage. The physical damage is more easily prevented. Make sure she eats reasonably and exercises, avoiding sugar, junk, alcohol, cigarettes, and drugs. There's no shortage of such women.

Gallop bravely, oh noble white knight to save her from herself before she does something rash and predictable!

Mental and spiritual damage are trickier. Once she gives up, no longer caring about good results, curious about life, or believing in eternal right, the rotten foundation can sustain nothing.

Perhaps damage is interesting. If you come to believe that, you will be rich with interesting drama to discover. Crazy is fun, until you realize you've hitched your dreams and aspirations to a crazy person, and now you live in an asylum of your own making.

Maybe she is still capable of intimacy, before the casual flings blurred differentiation and numbed away feeling. The brutal road wroughts permanent damage, and no one needs bring such things upon themselves.
