Stop doubting and start believing
When one has been played two many times or around negative people one may develop a negative attitude. We have a feeling that a guy we like likes us but in the back of our minds we say "He is just being friendly."
If you find yourself doing that then stop right now. The guy you like could like you back. If you find yourself getting excited over a guy continue. Don't worry about getting dissapointed. Not all guys are the same.
Not all guys are not going to call you when they get your number. Not all guys are going to pay attention to you then all of a sudden stop. If a guy does that then he is a player or has biopolar. When a guy likes a girl he will pursue her even if it takes awhile.
The guy you like could chose you. If you see a guy get excited to see you don't think about the ones that ignored you. When a guy gets excited to see a girl he probablly likes her. So don't doubt it.
The law of attraction states that when you doubt or fear it will happen. So if you want to be alone then keep on doubting and living in fear. If you want the chance at true love believe. Believe with all your heart that the person you like likes you back. Keep on believing and sooner or later he will finally ask you out.
