no he probably just doesn't like you at all
be a friend. its that easy. tho i dont see why you're trying to hide your feelings... I do not understand why you would just not tell her how you feel unless she is taken of course. However, in order to not show your feelings for her, you have to avoid talking nervously or showing her that you are intimidated by her. Do not stalk her or follow her around too much. Talk just as you would talk to any other girl that you do not have feelings for.
does it mean he likes you and he is trying to show it?
If you have really amazing feelings for him that you never want to let him go, then tell him. Tell him how much he means to you, tell him how much you love him and how much you would do for him and how he's your one and only always. show your feelings. let it all out. To a good relationship is communicating. Oh and tell him how much you loath and adore him.
Show him/her signs that you have feelings towards him/her.
He is probably trying to show you he is taken without hurting your feelings. Try to move on , you deserve a guy who wants you and who doesn't have a girlfriend.
Just tell her your feelings.
it means that he's in love with you or he's trying to show you his real feeling's
Empathy
Hang out with her and give her compliments but not too much she'll get annoyed.
Exclamatory sentences show strong feelings.
Do something nice and show how much she means to you or express your feelings towards her.
No they show feelings in the sea of monsters.
