She always smiles when she sees me and talks to me nicely but I don't know if she makes this to show me that she likes me or not.
When I see her talking to a group of guys she knows I become really irritated and jealous.
I don't know what I have to do to impress her.
Also I feel that I'm useless and don't deserve her.
I don't know if she considers me a friend or a brother I don't want to be friend zoned.
Do you think that she really likes me?
