It has often been discussed on WP that Aspies often get along better socially with people significantly younger or older than them, especially when they are a relatively independent minded Aspie.
How far could this translate into a better chance romantically, when someone is of a significantly different age? No doubt the partner would have to be similarly independently minded (that is, far from being a herd mentality member of society). If people get along with others not their own age e.g. let's say for the sake of argument I'm 35, and my friends tend to be aged around 20 and around 55-60, can it be the same regarding chances with romantic partners? Most people wish to keep within a conventional age range compared to themselves though.
In one of the popular books about AS, probably Tony Attwood's Complete Guide to Asperger Syndrome, there was a mention of a 22-year old male Aspie who had a girlfriend aged 72, and regularly beat her. Apart from the domestic violence issue, and concentrating on the age difference, a tone of sheer consternation and incredulity was expressed in the publication about the age difference. This sort of tone was unhealthy, as if it was more serious than the violence (if it wasn't in fact Tony Attwood I apologise to him)! Instead I'd encourage the age difference as a healthy thing if this is how people are able to connect as potential partners and if this is what it takes.
Please note I'm talking purely about adult-adult relationships here, of whatever age. Nothing involving underage.
