I'm going to complain about my husband's travel job
Is your husband travelling too much for his job?
Because I don't like it when he work in a far away place
It can be hard to be away from your partner. Maybe instead of complaining you can discuss with your partner ways to spend more time together. It might help ease your loneliness while he's away.
I'm going to get him fired questioning whether he should be doing this
That's not how a long distance relationship works. If your husband is working, you should be thankful he is helping to provide for the both of you. You could ask him to relocate to a closer job and maybe take a vacation to just relax a bit with him.
