Do guys act awkward if they don't like you and think you fancy them?

Yes, some guys may act awkward if they don't like you but sense that you have feelings for them. This awkwardness can stem from discomfort in navigating the situation and wanting to avoid leading you on. They might become distant or fidgety, trying to signal their lack of interest while also being considerate of your feelings. Everyone's response can vary, though, depending on their personality and communication style.
