Reddit mentions of Unmasking the Face: A Guide to Recognizing Emotions From Facial Expressions

I recommend some books on body language.

I'm currently reading The Definitive Book of Body Language

I have also read What Every BODY is Saying

I recommend both of them.

The first book is more about general body language, body language in business, and body language is courting. The second book is about lying and catching people lie.

There is also this book: Unmasking the Face: A Guide to Recognizing Emotions From Facial Expressions which I haven't read yet, but it looks good.

if you can memorize this sort of stuff, then read this free book on body language. you might like What Every Body Is Saying better, because they have actual photographs of people. I can't say for sure, because I am not very familiar with autism.

Also, I know that you say you've studied facial expressions, but Unmasking the Face has many great explanations of how the main facial expressions work, including masked expressions (such as a sad person trying not to appear sad)

If you say something that doesn't make sense and people laugh, you can either laugh with them or keep a straight face. That will get you out of most situations, because in addition to people not always saying what they mean, they also are nervous to ask for clarification, and will usually assume a positive intent or understanding.

Another book that might help you a great deal is Games People Play. It's based on Transactional Analysis, a very simple model of human behavior. Transactional Analysis defines a "Game" as a complex interaction with an ulterior motive, such as inviting someone to your room for a cup of coffee. You could familiarize yourself with common games, and it might help you.

EDIT: also, are you in touch with autism support groups of any kind? they may be able to help you more than people on the internet, since they will have experience with other autistic people.

A lot (not all) of TRP tries to teach you that LTR's are wrong and some try to berate you for the effort, however such isn't the case.

What you're experiencing is a form of oneitis, and a form of a lack of Abundance Mentality. Most of the things you will find on TRP do not deal with love - rather 99% of it is the plate theory. While I wont say such is wrong, it has little significance for someone not looking to fuck a different woman every night, and just wants to find someone suitable for companionship.

You need to realize that these "feelings" you have over this woman, could potentially happen with anyone, and there is nothing that makers her special from the rest of the female population. Once you start habitually and consciously retaining this information, your Abundance Mentality development will happen quickly. If you were as alpha and had such good luck with women as you make it seem, you would have no problem separating sex and emotion.

Plus, as other commentators said this lack of separation tends you to emit "beta" Like behaviors when you are entranced by a woman. So the problem here is more likely your behavior and the (probably) sudden change in how you treat a woman that scares her. Identify your actions, your habits and the things that you do that she does and doesn't like (and this is with all women, and learning body language can help with this. I recommend reading up on some Paul Eckman watching the Lie to Me Series on netflix might help with such too, It's a show I'd recommend everyone on this subreddit watch.
This is the type of thing I help figure out/deal with on my blog, so you can PM me if you have any questions or concerns.

Side note: I feel like you need to read the Bitch Hierarchy Guide that's stickied to this subreddit a few times, one thing he made important was this - sex does not affect a woman's level on the ladder - which I saw was a problem of yours.

a good resource for expressions

Its what the show "lie to me" is based on.

Buy any book by Paul Ekman. The one I bought is here, now my friends call me "The Mentalist".
