Do you know what a red flag is? Red flag is a guy being inconsistent. Red flag is not a guy who is being shy and not being able to kiss you. When you notice that this guy is trembling and he can’t even kiss you, do him a favor and just go for it and you’re sort of projecting your own red flags on the guy. You’re misinterpreting everything. He’s not trying to mess with you, he’s not trying to get revenge, he’s just being himself.
