A good friend of mine has Asperger's. His name is Drew. When he was diagnosed, his family watched an informational video that stated people with autism shouldn't date until their adults. 0.o

 Regardless, his girlfriend is his best friend dating back many years. They are now juniors in high school, and met in seventh grade. Drew met Em when his family moved to a suburb in Wisconsin from St. Louis. Em was the first classmate to befriend him, though she had multiple boyfriends in the early years of their friendship. Drew had a girlfriend his freshman year, as well. When they broke it off, he aknowledged his true feelings for Em.

Unfortunately, Em moved to another town sophomore year. Neither of them have driver's licenses. It is not uncommon for Drew to bike the long distance on half-days of school. He loves country music andplays songs for Em- some that he has written. Em is a tom boy. She loves camping, horseback riding, and rock climbing. Drew likes to plan their "adventures", and constantly ask for mine and others approval. He wants to make sure that she absoluely LOVES whatever he has planned.

I have Aspergers. I have been married for nearly 30 years. I think our marriage works because my wife knows her strengths and my weakness and organises things accordingly.

She has given up on expecting me to understand  romance but finds my attempts to grasp the concept amusing. On the other hand I am honest and loyal (supportive if made aware of a need to be) almost never late.

Every relationship involves give and take but some of us need to have things pointed clearly pointed out to us. I am perfectly willing to do things but it doesn't always occur to me to do them.

Seeing your personal info, you say you enjoy sarcasm, making people laugh, and don't keep a schedule.  Most aspies take everything literally so they take sarcasm seriously.  Similarly, many won't share or understand your sense of humour.  Some also prefer the pattern of a regular schedule.

Many aspies have difficulty communicating feelings and emotions and picking up on your facial or body expressions.  So if you're gonna be upset when he doesn't seem to be paying attention to your moods or picking up on your subtle hints, you may be disappointed often.  If he states things somewhat bluntly or awkwardly about you, he might see it as being matter of fact, and not really critical.  So ask questions, before taking offence.  Similarly, if he rambles on about a pet interest, he probably won't take offence if you change the subject.  If you're in a group, don't be rude and say, "No one is interested in that," since obviously your statement would be false since he knows that he is interested in whatever. 

If you get more serious someday, you may want to get married, but he may not seem to be making any moves.  He may be in a rut and just need prodding.  He's more likely to take direct questions without feeling scared off than most guys, so if he isn't ready and you ask him when he thinks he'd be ready to get married, you likely won't scare him off forever.

In other words you need to be a skilled communicator to keep the relationship working best.  If you are being sarcastic, you may need to use some obvious signal like blinking, and make sure that he knows that it's the signal and consistently use it.  Don't read things into what he says, listen to what he says and ask direct questions before getting upset with him.  Don't be too subtle when you talk, speak simply and directly.  I guess I could summarise that even more: Don't read between the lines and don't assume that he can/should/will read between the lines either.
