don't read her mind. read her actions. It's true u are too fast.
There are some indications she has some liking for u.
1st, she did not reject your invitation to go out. She did not
break the date. She's giving u her time and chance to evaluate a
possible romance.
2nd, she did not reject you holding her hand. But you made a
mistake by trying to touch her. Let her touch u instead.
3rd, where did u kiss her? lips or face? If it's the lips u got a
good chance dude. If u tried to kiss her but she turned the face
around to let u kiss her cheeks, well...not so good.
4th, Can u be more specific by saying she doesnt show affection for
u? She doesnt want to touch u or doesnt laugh at ur stupid jokes
when instead, she looks bored when u are telling jokes using a Mark
Lee's face?
5th, and stop calling her...it's a huge turn off for girls..at
least in the beginning when u hardly know someone.
