It's a big misconception in the community that by telling a girl you like her you look needy. It's utterly false. Well, it depends when. If you tell a girl you like simply because you like her but you're not going to stand there and hope she likes you back then this is Alpha behavior. Meaning you tell her you like her but at the same time is willing to move on if it doesn't work. On the other hand if you tell a girl you like her and are looking for her reaction and basing your next action based on what she has to say, it does look needy. Now, if you like her and you don't say anything it is a portrayal of the worst kind of neediness ever. Because girls can sense if you like them even if you hide it. And the fact that you're hiding it shows you do not express your feeling which is totally not alpha.
