There was a guy I knew who was really really hitting onto me. So instead of telling him I wasn't interested, I made up a boyfriend to put him off.
Duncan (who lived in Scotland) was a student too, his local job was cutting down trees for logs for his local pub (I mean, who'd believe that?) and because he lived so remotely he didn't have Internet access, so wasn't on Myspace (which was all the rage in those times). We'd also been going out for three years before-hand, I just, y'know, hadn't mentioned it til now. He was really nice, came to visit me over Valentines, sent me flowers, etc etc.
Meanwhile, I actually did get a boyfriend (a real-life one) so I told my 'stalker' (as he became known to my friends) I was cheating on Duncan.. This went on for some time and eventually I "dumped Duncan" for my current boyfriend, who was finding all this hilarious. Of course, my friends got up-to-the-minute updates over MSN (which was also the rage at the time), some of the conversations we had were hilarious.
I have reason to believe my stalker still doesn't know this was a lie, I haven't spoken to him in a long time ever since I told him to leave me alone (which I should have done in the first place, but then again - this was much more fun!)
Edit:
Yes it was a bad thing to do. This was over three years ago now and I'd like to think that I've grown up since then. I guess the lesson I've learnt is that it's easier to tell the truth in the long run, I probably did hurt his feelings and I do sometimes feel bad about it.
I missed out a lot of details however, such as texting me all the time, following me around and writing love songs about me. It got to the point where being polite just wasn't working and I guess I just tried to get out of the situation the easiest way I could.
Yes I know you'll just come back to me anyway saying I shouldn't of done it - I did though and I can't really turn back time now.
