Yes yes. This will certainly help! Or maybe, you will want to do
the reverse - Show her all the attention that she ever needs; I
suspect that she might be doing it just to irritate you, perhaps
because she knows you hate that kind of attention. Or she has
genuine feelings for you
Anyway, ask yourself, if you do have any feelings for her at all? I
mean, from your description, it seems that you really do have a
pretty bad impression of that girl. Perhaps view it more
positively? I mean, when you are negative about something, your
view is block and thus you'll tend to see only the bad side of
it.
I can tell that you are the sort of guy that will get embarassed
pretty quickly. Perhaps you want to use this opportunity to change
it? You know, you will lose out a lot by being shy/easily
embarassed e.g. ever been in a stituation where there is the last
piece of chicken wing left and you friend asks if you want it. You
do, but is shy to take it. So you lie that you don't want it. In
the end, your friend takes it. You have just lost something. If
this was bigger, in monetary terms, you would have lost big
time.
