I feel ye. Last year I was also diagnosed with Autism Spectrum Disorder. It doesn't mean yer annoyin', quite the opposite in your case, actually!
Havin' autism doesn't make you, me or anyone else any less social necessarily. For instance, I was diagnosed with mild on the spectrum because I don't make eye contact or open up to new people. I mean, I'm probably annoyin' to some people, but tl;dr: Don't let the label get to you. You're the same wonderful person as you were before bein' diagnosed.
Woo, that was ranty. Anyways, onto yer questions.
~do i come off as annoying to you?
Absolutely not. Believe me, I actually get annoyed very easily, and a lot of other members can get on my nerves; but never you. Not even in the slightest.
~is there anything that i do that you dislike..?
Not that I can think of, so no.
~what would you consider our relationship status to be? (friends, neutral, etc)
As much as I'd love to proclaim friendship, as we don't talk too often (yet <3); I'd like to call you a friendly acquaintance.
~am i too nice?
No such thing as too nice, love.
~do i seem like i wish to be the center of attention to you?
Again, not in the slightest.
