My straight married friend at work flirts and hits on me a lot, especially once he realized I thought he was cute. I imagine if anything happened from it that I'd be blamed for taking advantage of him. I think the whole vibe is gross, and this kind of game playing is a total turn-off. I hate predatory guys like that. I don't find him cute now, that's for sure. I'm avoiding him and looking for another job. He should call his wife.
