Love and lust will come and go like the tide, but trust holds it all together. Broken trust is very, very hard to mend.
We all marry for "security and benefits", among other things. Marrying military means you might lose your spouse for extended periods...... or permanently. I guess for some people that's a plus but for most it sucks.
Try not to get so distracted by this that you forget to cover your and your buddies asses. Good luck and thanks.
