Have you ever had doubt about someone?

Many times, and the one time I refused to listen to my doubts it led me into a disastrous marriage.....!!

Yes, Everyone.

Keep your eye on them, their true colors will show up soon enough. The few that turn out to be sincere, trustworthy, and honest, I form lifelong friendships with.

Of course. Listen to your feelings and by all means, don't ignore them. God is trying to warn you and guide you in this way.
