Gunships have always been and will always be a high demand low density asset. As a result the Ops tempo can be higher than most, especially in times of conflict (always). That being said, there are other platforms that have a higher ops tempo. Gunship squadrons tend to be very tight and the families have a strong social structure that provides balance and support when you are gone. Having done this gig for a long time, if she is a reasonable woman, she will be just fine.
If you've put all this work into becoming a pilot, I would suggest you follow your dreams.
