As long as you're dating, I'd say no, no need to disclose.
If you actually were to start talking about marriage, I'd say not only do you need to disclose, but she's got to understand exactly what it is. As aspies, we can be pretty good at faking it, and when dating, there's an enormous incentive to fake it correctly. But it's not something that can be done 100% of the time for an entire lifetime.
