crazy lecturer...

he is my lecturer in my uni, i really hate his subject...i think i dont hv any talent on it...but i keep trying!
one day he talk with me in the class, he talks about last nite soccer match (because his class always in monday) and we're getting "cool" and the weirdest many of my friend said he put "attention" to me...and i thought they r over react because what we're talk about only those general stuff like sport, music, etc.
one day he ask me to come with him to a music concert, i thought he was kiddin' so i answer with a big laugh and told him "ooh...sorry i dont wanna go with u, im affraid ur GF angry hehehe.."
he told me "i dont have GF" and i just do stupid laugh..(ha.ha.ha)
i dunno that he take it so seriously
the next day, it was raining after his class's break...i cant go home because i didnt drive at that day...he come to me and ask "its raining i bet u cant go home because i saw u didnt bring any umbrella" i told him "oh, i'd love to wait until the rain stop sir"
he keep trying to take me home...so i lie to him..i told him my home is soooo far away from his and i said im gonna go home with my bro soon.
i guess he didnt stop until here
, he keep try to "get closer" to me..by giving me lesson outside the class, make me as his assistant in almost every class in my major , help him to check the exam, etc.
it getting bother me, in every his class the student already know "who i am" (the lecturer lover )even dean of my major
i heard from a friend of mine actually he already has GF...just call her name is A, A is my senior...but she's graduated a looong time ago...he (the lecturer) also my senior...but he also already graduated loooong time ago...they met when they were student in my uni and then have the relationship since then until now
because i feel soooooo bother with what he did...i know he's only a man...he could like any girl...but why me? im his student, and how he did "try to get closer" to me was in uni, in my capacity as his student.
i feel so angry because he kinda "use" me (maybe)
he taking advantage his capacity as my lecturer, even i know i got good mark in my exam i bet that is his "work" not mine.
im confuse! i never mean to teased the lecturer, im just try to be polite/nice to them, dont get it wrong please. also when in uni i didnt use the very sexy dress or being sooo pretty

huh...hope i can solve this problem..he really out of the rule!!
