depends sometimes they are acutely friendly
It might be wanting to play.
It is unhealthy to do that. You can ask him to stop that.
likes [inappropriate term for male sexual organ]
Pretty much, if a guy doesn't freak out and leave when you cry, he's either a great friend or he likes you, but he more than likely likes you.
sometimes we bite our lips because we are nurvous about something or it becomes a bad habbit so if you see a boy biting there lip and there staring at you that could mean he likes you
don't know but it happened to one of my knuckles and it is really sore
You tell him how you feel, but don't say it like you want to be mean to him. Let him down gently though! (Important fact)
Tattoos of stars on knuckles can have different meanings to them. They can have a nautical meaning or they can just be decorative.
She blew on you ok that's weird to answer your question yes yes yes she does like you it is obvious or she could be a friend but the blowing means flirting so yeah she likes you
No. Even though she flirts around with him doesn't mean she loves/likes him. Once in her description it said "Rouge has a crush on KNUCKLES THE ECHIDNA" or I think it was "Rouge only love interest is KNUCKLES THE ECHIDNA" Rouge only sees Shadow as a brother... a brother she never had and knuxouge sucks! SHADOUGE! :)
maybe it's shy or scared of you, try to gain it's trust by feeding it like treats it likes and talking to and petting it gently.
I would just reject him as gently as possible. I mean, he knows you have a boyfriend.. there's no out of the friend-zone for him.
