I think u just be normal... talk the way u talk online... Have a
good joke etc... If she's ur type.. like one said earlier.. u can
go for it if u like her... If she's not ur type... u still hv to
continue to be her friend of course...Be friendly...And whatever u
treat her is what she treats u in return...
Also... I think this depends on what ur intention is.. whether it's
just a normal friend.. or an occassion date or maybe... for sex??
What ever it is.. u have to tell her also, be honest!... Be careful
because sometimes things can be messy, even for a friendship
started from online chat... (last time i got a friend almost got
divorce with his wife just because of one of his online chat friend
fell in love with him,the gal didnt know that he is married becoz
my friend was dishonest)
Maybe in the future after u get to know her better, u want to be
her boyfriend... still u hv to observe clearly... whether she wants
to be with ur partner also or that she's just trying to add her
online friend collection??
