Pls help! What shall I do!

today i encountered an incident which really scared me out of wits, so i put it up and hope to gather some suggestions from friends who read my blog. T_T

i met a guy when i was on my way to wash's place for dinner. he was looking for sth in New College and approached me for help. i could not understand him most of the time due to his strong accent, but managed to catch some key words. he was looking for a computer lab to do his paper. apparently new college computer center was closed already, so i told him he could find one in the new college library. so i showed him the way and was ready to leave him. he thanked me many times and kissed me on the back of my hand! gosh... i don't know... i've never been treated this way so i was quite stunned at first. then i thought, ok, this might be his culture and tradition, so i didn't really care about it.

when i just turned away i heard him swearing back at the library entrance. too bad it was closed too. i was quite sorry for him. he appeared aggitated so i surmised that it must be very urgent to use a computer. it was really a bad decision but i decided to show him the way to Gerstein Library which is 10 minutes away. well, so we were on the way. i didn't know what i was thinking at that time, i just shouldn't be that nice to a stranger at all!!! he appeared very enthusiastic when i answered him where i'm from, and began to tell me some weird stuff. his strong accent made the communicatio very difficult. i could only catch a bit, furthermore i was totally uninterested at the stuff he was telling me, like he's a russian, there are bad and good russians, he can shoot ppl he dislikes, but he can be very nice to ppl he likes... i thought it was funny at first, then realised things were not so simple later.

i pointed to him the way to gerstein, but he expressed the wish that if i could take him there. so i took him there and was ready to leave again. then he started saying things like "pls, don't go, i don't want to lose you. i'll wait for you here, one hour, two hours, pls come back.." by then i begin to realise the severity of what i've done. i shouldn't be too nice to a stranger. showing him the way was ok, but taking him there might be too much. but seriously, a normal person wouldn't say these things to a girl met for less than half an hour. so i told him repeatedly that sorry i must go now blah. then he forced me to note down his phone number and said "call me, anytime, i'll wait for you. otherwise i'll go and find you. promise." i was quite scared by his words and he just kept on making me promise to call him (more than 5 times at least). gosh, what i've done! i should just leave him at the new college library!

so when i met wash i was half an hour late. i was so scared cos i couldn't stop making connection between his words of shooting someone if he wanted and coming to find me if i don't call him. wash told me not to call. but what i'm afraid is, if i don't call him and he really comes to find me, what can happen??? guys, what shall i do???
