So last July, I (18M) met this girl online (18F). We got along kind of well, talking pretty much only over text. For context, I am autistic, and am quite socially awkward.
I have a tendency to do "bits" when talking to people. One of these was narrating everything she said, which she seemed bothered with but never said anything too dramatic against. Other than that, I'd usually reply to her in full sentences, would have my auto-caps on, and sometimes, I use a big word here and there (I think the other day, I asked about her idiosyncracies, and she left me on read for a few hours).
After some time, she ended up ghosting me, and until now, I wasn't sure why. I always thought she might have found me odd, but not knowing how's been bothering me for months. Recently I decided to text her again.
It's going well, but today the topic of social skills came up. I talked about how I struggle socially, and at some point said something like "(name), of course I'm excited to talk to you! Talking to (name) is a special occasion." I then mentioned I used to do the whole narration thing, and that I was sure she was tired of it. She then said that that's a reason she stopped talking to me, and it didn't help that we only talked over text, mostly talked about boring topics, and she wasn't in a good mental state at the time. Most notably though, she said that I talked "too businessy". I'm not truly sure what she means by this, but I see how a lot of my mannerisms can be strange. It's common with people with autism, and to clarify I'm also sure she didn't mean this in a judging way since she's neurodivergent herself.
I get very nervous when she replies to me and will sometimes spend 3-4 hours figuring out what to say back to her. I stress when she sends something a sentence or less long. I can't really get the conversations out of surface level mundane topics, but this is not because she's not interested in talking to me. She usually replies quick, and seems to actually want to talk, often writing more than a few sentences. If I ask my friends for advice on what to say, if they tell me to say anything shorter than about a sentence, think "lol that's interesting", I'll end up writing something like "Well, I find that interesting. Have you always liked (topic)?". Among IRL peers, I act far too casual and even childish. This only seems to happen with people I don't know IRL, or am too interested in talking to. How do I talk to people without sounding "businessy", and are there other takeaways?
