Everyone including the biology major is incorrect, it's almost never a 50-50% split genetically, that's just close to the average.
That being said, no- nobody has even tried to make a lopsided mix favoring one parent over another beyond crispr gene deletion, and that's extremely rare as pretty much every nation on the planet freaked out when China tried it, but they were trying to eliminate a disease trait, not favor one sex over another percentage wise.
Aspergers isn't that bad of a disorder and if the father isn't a carrier, kid is much less likely to have it with your severity, or at all. You just have low serotonin and dopamine right now, and it is making you very depressed and leading you to unreasonable fears.
This was the subject of a Star Trek Voyager episode: Season 7, Episode 12 Lineage. She kept trying to get the doctor to delete her DNA from the baby.

This was also Michael Jackson's problem when he had a white woman give birth to "his" child, a fully white baby named "Blanket", which just ruined the life of what otherwise wouod of been a normal child.
The problem isn't passing on Aspergers. It's a managable disorder, and the kid is unlikely to have it to your degree. The problem is a paychological affliction in you, and it isn't aspergers. It's your own self loathing. You gotta get over yourself and just accept nature is going to do it's thing. You are in a relationship with a man, a child is the natural result. You'll likely be a decent mother. Don't stress it now, save that for the delivery room.
