I've gotten much better, in general, with women over the last year, but I still have much to learn. That being said, this isn't necessarily related with pick up but just women in general.

I have a bad habit of being "that" guy. For example, there's a girl in my office who gets along fine with everyone, but I feel is creeped out by me specifically. Or at least uncomfortable. There was a party she had that most everyone was invited to, and as a result I got invited through a friend, not her. She lives with another coworker for some background.

She didn't care for any interaction I tried to initiate with her the whole night. We get along well at work, and I have flirted with her once or twice, but she has a boyfriend so I don't take it further than a casual talk.

The reason I'm asking for insight is because this is a recurring issue of mine. It bugs me a little bit, I don't like the girl at all, but I'd like some theories as to why this continues to happen.

Thanks seddit!
