I'm going to buck the trend a bit with something that might be unpopular.

I think you should tell her as soon as possible. (I.e. on your next date - not right this second.)

I tend to find that the harder it is to tell someone something, the more important it is to tell them.

To examine some of the likely scenarios:

• If you tell her now and she has a problem with it, then you'll both be upset for a while but you'll move on.
• If you wait until you're a lot closer and she has a problem with it, then it's going to hurt a lot more for both of you.
• If you tell her later and she's fine with it, then that's good.
• If you tell her now and she's fine with it, then it's a weight off your shoulders and she'll be able to understand some of your behaviours better.

She might not know what aspergers is, in which case you'll have to explain it to her.

Try to keep the explanation brief and not go too far into detail, otherwise you run the risk of making it seem like the entire date was just about you having aspergers.

When you're done explaining, ask her if she has any questions and reassure her that you won't be offended, that way it's a two-way conversation and she'll fell like you're including her rather than dumping something major on her.

Getting her to ask questions is also a good way to find out what she's like. For example some of her questions might be driven by concern, which shows she's probably a caring person. If she's more concerned about if it impacts your job then it may be a hint that she's more interested in your wallet. (These are generalisations, so bear them in mind but don't rely on them alone.)

Importantly, when she doesn't have any more questions, move on to a different topic to make sure that isn't the only thing she remembers about the evening. You might want to ask her once at the end something along the lines of "So you're ok with the whole aspergers thing? I'm sorry if it was a bit of a shock." (i.e. ask her how she feels and sound reassuring).

Hopefully if she's not ok with it that will be the point where she says "Actually I don't think we should see each other again", but most likely she will just say "Yeah, it's not a problem, don't worry about it".

Try to make sure you only ask her that she's ok with it once or twice. If you keep asking she might start to worry that it is a big deal or that you're insecure and looking for someone to cling to.

(I normally have a self-imposed rule of not offering dating advice, but since this is more along the lines of "how do I tell someone I have a psychiactric disorder?" I made an exception.)
