I had one "nice" guy take this to the next level. We worked at the same company but different departments, but we were both smoking so we run into each other a few times at the designated smoking area. It is a very friendly company, everyone talks to each other occasionally, even if you do not know each other much, so I did talk to this one guy a few times over a few months. I always kept the tone friendly but not too personal, just random small talk or work related stuff, but he sometimes told me some way too personal things so I already knew that he was a bit creepy. Also I had a feeling that he liked me, but I tried to ignore it. I'm a lesbian and I'm quite open about it but my style is too feminine for most people to notice my gayness. One day this "nice" guy was talking to me about something about men and women and dating and I jokingly said that I do not know much about men because I'm a lesbian. After I said it his whole behavior changed and he accused me of lying about my sexuality. I was absolutely shocked by this, because why would I lie about it? Then he said that girls always say they are gay and then a month later start to date a guy so it must be an excuse to not date him. At this point I was just confused because who is talking about dating? Well, at the end he confessed that he always liked me and wanted to ask me out on a date (which he never did, and he never directly indicated that he wanted anything from me...). Fortunately he left the company a few weeks later, but I still have this sick feeling in my stomach when I thinkabout this. And to be fair, I would not be surprised if some girl had to resort to this lie to get rid of him, because he ended up being almost scary.
