Sorry to read that Elsa, that guy sounds like a real jerk. Just remember it's not what he says that defines the kind of person you are. People will be hateful and mean, but don't let them bring you down.
As per the question, with me it's not so much. I kind of had an experience where I came out to a guy recently and it just went ice cold, although without calling me names or being mean. I didn't really feel like "OMG, I'm ugly, nobody will date me."I actually felt like "if he's not comfortable with it, then eh." It's kind of a defense mechanism, but some people won't date smokers, the unemployed, outside their race, etc. If they're not comfortable dating a trans-person, I try not to get too offended. Such is life.
Also, my policy is to come out to them before the first kiss, so that I'm not thought to be "leading anyone on." I think you coming out when you did was about as close to ideal as possible. Dude needs to stop being a tool.
