I think you are afraid that the person you like will lie to you.
It's just a psychological hint of self. I don't think this is a prophecy or anything. If you keep thinking about it, it may come true. Because you have this idea, it means that either you perceive some dangerous signs around you, and your defense consciousness has played a role. Either you are imagining things, but your active hostility or avoidance consciousness may be detected by the other party and betrayed.
