My husband just got promoted and he is gonna be travelling frequently, short trips though. I should be supportive but I'm getting freaked out on what may possibly happen on business trips. Am I being overly paranoid?

Talk to your partner about it perhaps. And have more faith in you and your relationship with your partner! Getting promoted should be something to be celebrated

Trust, is the most important key for healthy relationship. Explain the insecurity to him and talk about the same.

Maybe its a sudden change , you probably need some time to adjust to it.

You should trust him. If you truly love him, trust in him.

thanks
