Is it ok to marry a man with an autism spectrum disorder?

Yes: If you love him and understand autism and now how to communicate with him.....He is very lucky indeed, and so are you to have found love and be willing to do what it takes to make the marriage successful. When you go into a relationship (or any situation) eyes wide open and prepared and willing to do the work and understand all the ramifications, it is a very beneficial situation.

Depends: "it depends if he wants to marry you." there are so many variables that are unknown in any marriage. Autistic people can have happy productive lives with a partner. Make sure you communicate and have realistic expectations about the future. There are adult support groups for adults with autism.
