I was going to write something much longer, but I decided it'd be best to ask for a little bit of "the story". I understand if you aren't comfortable telling us more, and I won't ask you for anything after this post if you don't want to share anything about your situation.
This just doesn't strike me as one of the threads people post out of innocent curiosity or wanting to engage their community on any aspect of life for the mere sake of it. No, it just feels like there is something going on that is really bothering you.
The brevity of the OP kind of confused me at first and I've rewritten my response several times. It was just hard to figure out what you meant, probably just me though. I looked at your profile a little and that helped me. (Hopefully.)
That all said, you say that he is basically ghosting you suddenly? You used the words "love bomb" and "dispose", so there has been enough of a history to consider yourself in a relationship but not too long that you'd say "leaving you" "abandoning you" etc as most people say when there's been a serious, we-share-the-dog-house-and-pizzas relationship.
Is that fair or am I reading this wrong?
Now it is totally possible for an aspie to realize a little too late that a person is not right for them during the dating process and wussy out and avoid somebody because they don't know how to express themselves. I don't get this feeling though.
You said "love bombing" which is a very manipulative and mean thing. Is that exactly what happened? Were they very affectionate, comparatively to every person you've ever dated? And now they are avoiding you completely? For how long now? We can also get caught up in other life-related things, realize we've been negligent and feel so guilty we avoid people, making the situation worse. But that wouldn't make sense, since I'm assuming you have been trying to initiate contact.
Did something happen in the time before they went completely dark on you? Something that might have upset them or made them feel bad about themselves? Even if it wasn't intentional and wouldn't upset a normal person. Anything outside your relationship maybe?
Also a few more questions: do you guys know each other online or irl? When did you find out he was on the spectrum? Is it a hunch he had or was he diagnosed, I mean. If you know anything about ASD, I guess you can judge how much he matches the profile for yourself. Lot's of people are misdiagnosed. A friend of mine for example, was dating a guy they thought was autistic but he hit her, was violently jealous and clingy and controlling. When she left him, he stalked her both in real life and online, harassed her over the phone, would threaten to kill himself if she didn't come back. You get the idea. Point of this story is that he wasn't autistic, he had Borderline Personality Disorder. Way way different.
Love bombing luckily is not something that I associate with toxic relationships and the sadists that go that far. It's more for the narcissistic type that have no respect for women and so treat courting them like a sport while reveling in some high they get imagining their ex being such a heart broken mess trying to get them back. So if you really feel that you have been discarded by a wad like this, don't give him the ego-inflating satisfaction of looking like you are desperately chasing after him. Heck, if you were really love bombed, he may have even made the whole asperger's thing up to make you sympathetic for him and maybe even feel like you were his dearest most compassionate angel, like a movie clique. (My friend's abusive ex made her feel that way.)
No matter what, the out pouring here should make it self-evident that you are supported and you have people to talk to. So don't be shy.
