You can work on facial expression and body language intellectually, to gain the abilities in interacting with other people that allistic people have instinctively. I know, because I did this. Working out how non-verbal communication functions is possible. It is especially useful for recognising the subtle signs that a woman finds you attractive. I didn't have a meaningful romantic relationship before I was thirty, but was married at thirty five. Sometimes effort pays off.
Does it matter? Not everyone needs to date or be in a relationship.
There's a whole neurotypical/heteronormative/programmed way of thinking that we are somehow unfulfilled unless we have XYZ. We don't have to date, we don't have to have a partner, marry, have kids or anything else. It's fine to be who you are (as long as you're not hurting anyone else imo).
PS. The typo in Anonymous is driving me nuts.
Allow me to put on my cynical hat. Most human beings are shallow and are atracted to shallow atributes in a partner, at least in the first instance. No matter how unatractive you are or how weird you come off as you would find some women atracted to you if you had tons of money or the body of a althleet / body builder. If you were the leader of a popular rock band. I'm not saying it's not unfair but maybe you should work on improving those shallow atributes that atract women to the point where it compensates for any 'weird vibes' you give off.
I work as a TV and film extra, and also play guitar, I'm just trying to find other like-minded, committed musicians to start a band with, which is hard lol and I also work in one of my local supermarkets. I do like hillwalking, but I'm not sure if there's any other ramblers as weird as me
Look into volunteering in your local area, or joining an adult course at college. You'll meet people and potentially make friends that way. If you live in the UK, there are probably some rambling groups that accept people of all ages if you're into walking.
I'm also a weird geek who's not particularly good at much apart from having attention to detail and being a bit creative. I found a partner who's also a weird geek. There are others like you, you're not the anomaly you claim to be.
Yes, you keep telling us this but unfortunately there isn't much we can do about it if the replies you've had so far haven't made you feel any better about yourself. Maybe you could think about what you could change to increase your self esteem?
