[Master Chief]

OK, so recently I joined IRC and so far i LOVE it! but this guy (lets call him billy) has been kind of getting on my nerves....it all started when he called me on my cell phone one night. I found a number had called me that i didnt recpgnize so i called back, nobody answered except the answering machine, and it had billys vouce in it (apparently hes one of the IRC officers). i started freaking out and texted the number whos this and why u called. when i recieved no responce i called again and billy answered and i asked "excuse me did this number call me?" and he said "whos this?" and i said my name and he said "yes" and introduced himself as an IRC officer and said he called me to remind me that some forms for an uncoming conference was due he next day and i said ok but howd u get mah number and he said i put it on mah application then i rememebred i did and i said ok and said goodnight and thanked him for the reminder. then the next day i found out hes in my history class :/ but i didnt rele mind. then i becaome a little suspicious (idk why) and i asked a friend whos also in iRC with me and asked if bily called her to remind her of the forms and she said no. i aksed a couple others and said they werent aware of billy calling them. i got a lil uncomfortable that hed only call me but i ignored it again. then he texted me something a few weeks later i tried to open the text but i never did cuz it "failed to open" then i aksed a couple of others if billy texted them and they all said no. then the next day he called me (i have caller id so this time i recognized it) butt for me my number is private (my daddy put it on private when he bought me my cell phone idk why he did) and so even if someone has my number as a contact itll say private number. so i called billy and he never picked up and then a few minutes later he called me again but i didnt pick up cuz i had to go to bed. (he apparently knew i called cuz the next day he said that i called and he was all like is there something u need and i said no u called me first and i said my number was private and even if someone has my number as a contact ittll say private number and said whyd u call but he just shrugged and walked away..) so i asked a couple of people if billy called them and they all said no again. :/ then yesterday i needed to call him to ask him something about IRC and i texted him my question and he was all like, "whos this?" and explain he "got a new phone" and that he "doesnt have any old contacts yet" but i checked around turns out he never got a new phone. so idk why hed lie about that..then this morning i joined the iRC group page on facebook and juist now billy added me on facebook. i rejected his friend request tho (only add peiople i know) is billy stalking me? if so what can i do about the situation? help :'(

He isn't stalking you, he just has a crush on you. You need to tone it down and maybe give him a chance.

no one is stalking you.
