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?

How is your relationship with your husband? I think all marriage has to have trust. You should trust your husband. Is there anything that happened before that is causing your paranoia? If there hasn't been any reason or cause, then perhaps you should really tell yourself that you should trust your husband. You can also consider being honest with him and share your feelings. It is good and healthy to have these feelings acknowledged and addressed. My husband travels for work occasionally too but he has been really sweet to update me about what he does everyday and where he goes. We also have skype video calls. I trust him and I think your husband deserves your trust as well.
