She obviously refused me, but she sent her blessing on my birthday. Why?

When any girl is being chased, her psychology is very complicated. She may be happy, but she is a little scared. She has ambivalence towards the boy who intruded into her quiet life. She didn't mean to. Don't think she is testing you. She's actually fighting herself. She's afraid of being hurt.

Don't be afraid that your initiative will bring her disgust. If you don't take the initiative, she won't take the initiative, and it will fade slowly. If your initial confession is rejected by her, it is normal. Don't be discouraged. Who knows what this girl is thinking?

Maybe if you confess twice, she will be moved by you. Kind girls are easily moved.

If you encounter setbacks, leave immediately, never reply to this girl again, protect yourself tightly and lick the wound silently. When you are in pain, as everyone knows, that girl may regret it in her heart. Maybe she will secretly cry and regret rejecting you, and it will be sad to see your indifferent eyes again, but she won't tell you and won't let you come back to chase her. Your excessive self-esteem may hurt a girl's sensitive heart.

So I suggest that you should be brave enough to pursue the girl you like, and don't be so timid. One is to make people feel that you are not manly, and the other is to make people feel uncomfortable. However, the most important thing is: in the end, you will get nothing. Happiness is always earned by yourself!
