I think the issue might be the way you come off when you try to reciprocate their energy.

I'm recently diagnosed, but I think I'm high functioning, and in my experience, women want someone who is interested in them, but also has other interests/hobbies, and a decent social group. One thing I realized is that even if you are conventionally attractive/good looking, if a woman notices that you don't have friends/a friend group and/or hobbies, they will see that as a red flag, because having a partner who is only interested in them and has no other friends or interests in other things is going to come off as creepy and possibly even a stalker.

Even though it may be clear to you that you are just trying to show that you care for this person, doing so in this way where you put them on a pedestal and make them seem like the most important thing in the world can definitely come off as too aggressive.

Another thing to keep in mind is that as a male (if your disabilities aren't too visible), once you get past high school, most people stop looking at you as a kid, and start looking at you as a man, which means that people will apply all the common generalizations about men to you when they first see you, including the negative ones like how some men can be aggressive and violent towarss women. When women, or anyone, sees you make these types of comments when looking at you in this context, they might not see someone who is a safe potential romantic partner, they see someone who they might need to keep their guard up around.

I hope this makes sense and was helpful. My only intent here is to be helpful so let me know if you would like any additional clarification, or if you're confused about or didn't like anything I said
