Is it ok to share your insecurities with your husband/wife?

As far as cheating or anything goes? If there was absolutely no evidence or anything like that happening it was just something you were being paranoid about that might happen in the future b/c they were getting a new job or something? Should you just come out and say it to help relieve some stress or should you keep it inside? If your partner is very understanding do you think itd be ok to share your fears with them about cheating? no accusations or anything just saying your paranoid? I dont know. I think it might help me. My husband is very understanding I dont think he'd get upset but Id just like others opinions? thanks.
