Let's start with my favorite
1. "What if he get's deployed?'
I never understood what people meant by this. Do they expect me to say, "Oh if he gets deployed, I'm leaving." NO. If he gets deployed, I'm going to be the same thing I am doing now: supporting him and holding down the fort.
2. "Why are you complaining? You knew what you were getting into."
First of all, even the most knowledgeable military spouse will complain. There are things you cannot plan for and that you never envision happening to you, just as people do in the civilian world. That's like saying, "since you applied for that job, you knew what you were getting into, so I never want to hear you complain."
3. "My husband and I lived 2 hours away from each other in high school, we only saw each other once a week, so I totally know what you mean by long-distance."
If you have never endured long-distance in the military, you have no room to speak on the topic.
4. "What if he cheats on you while he's gone?"
Out of all of the things a spouse could be worried about while their service member is deployed, underway, or on a TDY, you want to now ask me what I would do if my husband cheated on me? How about ask how he's doing???? Wouldn't it be rude for me to ask what you would do if your husband cheated on you if he was on a business trip? Think about it.
5. "Oh he has left so many times, I'm sure you're used to it!"
No matter how many times my service member leaves home for duty, I'll never get used to it. Being away from the person you love is never comfortable for either person, but we do it because we have to.
6. "I don't know how you do it."
How I do what? Exactly what I said in my vows? I made a life-long promise to my husband that I would support him through everything, understand that life is unpredictable, remain loyal, and make every place we live feel like home. That shouldn't be much different from what you promise your husband?
7. "It must be great to have so much money!"
If I'm being 100% transparent, the military doesn't live a lavish lifestyle. You have enough to make it by and save moderately where you can. The military is full of average people, especially E-4 and below.
8. "I bet you can't wait until he gets out."
I promised him I would support his decisions from day one and if he wants to do 4 years and get out, that's great. If he wants to do 20 and retire, that's great too. We are not waiting until he separates from the military to really enjoy life, why not enjoy it now?
