Taking a break from dating, like taking a break from Internet forums, is sometimes a good idea until you feel ready to go back into the fray.
Distress about dating is not limited to autistic people. It's hard for many, perhaps most. And the phenomenon of sticking with a "good enough" relationship is known worldwide... also known as "settling."
I'd say date when you feel up to an interpersonal risk, and don't date when you don't. If you're already in a relationship, but it doesn't seem to be progressing, remind yourself that all growth entails risk. If a static situation meets your needs right now (and there's nothing wrong with that!), then don't take any risks. If you need more, gently push the subject and then decide what to do, based on the other person's reaction.
