Now is not the time

When you have been deployed for 3.5 months,
When your wife has been at home alone with 2 children, ages 5 and 2,
When she has only hired a baby sitter two times in those 3.5 months,
And has been without a break for over 2 months,

When she is at her wits end and ready to snap,

That is not the time to tell her that you want to re-enlist and stay in the military for another 3 years.

Not the time.
