One of the defining characteristics of Asperger's is the inability to "read" other people's expressions, not looking others in the eye and inability to make 'small talk', as well as social anxiety.  These all gang up to make it very hard to get a girl/boyfriend in the usual places such as nightclubs and parties.

One way around that is to meet someone online or as a penpal, and you get to know each other without Asperger's messing things up, by exchanging email, IM, telephone and/or regular postal mail.  Soon you may decide you really like each other, but you've never met in person! When you do finally meet in person, you already know each other well and Asperger's has less of an effect.  For example, inability to make smalltalk isn't so much of a problem since you already have several common interests or topics to talk about.

I'm thinking in particular of relationships where it would take quite a bit of effort to meet in person (such as flying halfway across the US (or the world!)), not something like meeting someone across town in a dating site, whom you decide to meet after a few days and emails.

So....  Do/did you have a 'significant other' whom you've only known online, or only online for a long period before meeting in person?  How did it work out?  Also, was he/she different in person than online?  Did the other person find you different in person than online?  How did your Asperger's affect the meeting?  Do I ask too many questions?

I've had 3 serious relationships in my life, all three were 'online', all three required airline tickets to meet, all three went well, and I finally married the last one.
