I'm anxious about my husband cheating
Do you think that your husband will cheat on you?
I've heard some rumors, but I'm not sure if they're true.
Worrying about someone cheating on  you can be understandable, but a good relationship requires trust. If you can't trust your husband, you should talk to him or get counseling.
I trust him enough but I'm just not sure about it.
I'm glad you trust him and if you truly do, then you shouldn't worry so much. However, if this issue continues to be a thing you should discuss your worries and talk with someone as a couple.
