hows its goin along, dude? 
- 1stly, I tink U r 1 darn LUCKY guy 2 hv a gal "absolutely
smitten" wif u....wow
wish i had a gorgoeus guy whos doin e same ...keke 
- N since u no intention 2 lead her on....then i wld suggest u do e
"MIA" act, n not to be even FRIENDS with her...becos between a pair
of Female/Male, its very tough 2 draw a
clear-cut line on "Purely Platonic" relationship
- Be a "Kind Jerk" for once, n sever even friendship with her if
she persists in wooing u (blush..geez i realli admire dat gals
perseverance). And provided U indeed harbour "zero liking" 2wards
her...cos u will lose a fren but solve ur prob IMMEDIATELY
- in short, e action to take (juz a wacky, but effective
suggestion)is to engage e help of ur female fren, ask her to call e
gal n conversation can be as follows
in
a nice tone, but firm manner)
Teleconversation goes sumting like tis:-
Pt 1=
"Hi BBB(ur admirer's name), Im XXX(ur name)'s girlfren, I saw your
sms to XXX N he has explained to me abt U pursuing him 4 a BGR. So,
can u give respect 2 OTHERS' freedom N Stop pestering him 4 a
relationship? HE N I R oredi in a relationship..
Pt 2=
I think XXX treats N values ur FRIENDSHIP, n if he sincerely wish 2
maintain e frenship. But do STOP pestering him for a BGR, cos he
already HAS ME.
He wants to tell u straight but at same time afraid u'll feel hurt.
So he wants mi 2 tell u on his behalf.
Pt 3:
Pls understand a fact dat love cant b FORCED, N he n I r 2gether
now...u will meet a good guy, so TAKE CARE n if u can, he will love
2 continue 2 be UR FREN. But strictly no "BGR" intent.
good bye"
100 % effective, but in any case, pls GIVe sum PRIDE for e poor gal
to salvage...im sure if u wish 4 her happiness, U can FORSAKE your
intention 2 be PURE friends with her,
becos it means N benefits u to hv anor fren, BUT for her, ITS jus
like a living TORTURE (if she's smitten wif u = INFATUATION)
B daring enuf 2 CUT ALL TIES....as time pass, she will 4get u,
confirmed.
Cheers
