Couldn't agree more.
When you are going to tell her tat, pls dun hesitate, and put it in
a tactful but firm way.
If she shuts you down for being lame and over-sensertive, which
could be expected, just laugh along with her, which also meant she
still wants this friendship to go on, but not any deeper.
If she is still persistant about it and behaving like something
snap inside of her, you could :
1) perhaps give in and have a try in this relationship
2) completely avoid her at all cost. e.g. ignoring her calls, avoid
eye contact, no conversation. The message needs to get into her
head. Also, ask her friendS for help, hopefully peer-pressure could
calm her down.
3)
