Well, even if she does not understand it yet, keep talkin (in easy words) about what you are doing and especially about her interests. She might get an interest in conversation when she gets the idea what she might need it for.

Sorry, I don't know any videos about autism.

But I've seen a documentary about a young german adolescent woman, who did quite well at school and then got a job (it's learning on a job, don't know the right vocabulary). After a short while she stopped communicating - completely! She was not diagnosed by then and her mother had a hell of a time to get through to her daughter. On tv the young woman saw something about aspergers and looked it up in internet and had herself diagnosed then. After that it went better, she found out, what she needed to prevent herself from overload.

What I want to say with that story is, that overloading might make it worse. I have much more problems now, that I'm single mother, than when being married (even having problems with my husband) and having help with the kids and getting the time off that I needed.

So just be careful with her. Why should one be social if not wanting/needing it at that age? Does your husband go to every social event you'd like him to go with you? Maybe that would be an argument? Maybe you would like to go to concerts/theatre and he doesn't or something like that? Would he force you to go to see soccer? Would he expect his best friend to go to watch Wimbledon if the friend was not interested? People like different things and if something is too boring or scary (like rollercoaster or ghost train) they can decide on their own. He would not force her to see scary films, wouldn't he? So why having her going to scary social events? Maybe you can find some arguments there.
