I have been going after a girl I work with for about a month now. I know this has been going on for too long, but the work relationship has held me back. She seems to respond well to negs and has shown much interest with her body language, but I can't seem to get over the hump. She seems to be a girl that only goes out with her girlfriends. We have attempted to hang out outside of work, but it rarely happens. She has invited me to her house casually, but we tried setting up times, they didn't work out. But this situation is getting to the point where I have been worrying excessively. It is a weird situation because I see her 4 times a week, but I think the only way to move this forward is either a bold move or become even more persistent. Any advice would be helpful
