Today I felt the urge to cheat on my husband.
Why would you feel the urge to cheat on your husband? What feelings are you having at the time?
I was very fearful about doing it, I don't expect others to care about that.
You made a good choice to not cheat on your husband. It's wise to think things over before you take an action that cannot be fixed. Actions like cheating is detrimental to any relationship.
I'm glad I didn't go through with it also.
This is good that you didn't act on those feelings. I would still recommend you get some marriage therapy to help out these issues that you're having.
