There is a guy I like at work. I am so confused about him. I started being interested in him a year ago and I asked him if he was married, etc. He said no he wasn't and that he wasn't dating anyone either. This January, I told him I was interested in him and he said he was engaged. I thought it couldn't be right so I asked people that know him. They said he was teasing me to make me jealous. I know that this guy is a really big teaser. He could be lying but how do I know and how can I find out?
