I Dont Understand What I Did Wrong

I Miscommunicate.... I can't communicate with people. Like yesterday i was IMing and I thought they wanted to follow a certain track of thought, but they kept ignoring me and losing place in the conversation. I was in the process of trying to understand something about them, maybe understand something about people in general. Then they got frustrated with me and cut it off. They didn't propose changing the subject, they didn't tell me to drop it, they didn't tell me what I was trying to understand, they just drop off and got angry. So obviously I'm no closer to understanding, and I feel like I need to know, I perseverate over knowledge. So understanding the break point in that convo, has gotten me rocking, stimming and... nothing that gets me closer to understanding.
