Oh thank goodness, I'm not the only one.
I have two online friends, and right now two IRL friends (including my fiancé).
I am as terrible with back and forth chatting online as I am IRL. The concept of general chit chat and small talk needs to just go away and never come back. Communicating in something other than infodumping takes a lot of effort.
Both online and IRL, I often feel panicked because I can't tell where social boundaries are and either come off as too invasive with my attention or too withdrawn. I don't know how much is too much or too little. I prefer other people approach me when they want to hang out/chat for the aforementioned reasons, which people interpret as not wanting to hang out, period.
I often trip myself up with trying to fit in. I pretend to like things I don't, which always fails, and I don't know why I can't seem to make myself stop. I used to talk about sex and drinking a lot because I thought that was what people liked to hear. I had a reputation as a drunken floozy for a while and didn't understand why. I spent a long, long time trying to present myself as very vulgar and kooky because it got laughs, not realizing how offensive and off putting I was until I got called out by someone I looked up to. It wasn't completely an act, but I turned it up from maybe five to eleven.
I don't know how to act to fit in. Being myself doesn't feel like an option. I am stony and blunt, so I'm kinda regarded as an ice queen when I am >_<
I honestly have no idea how I have the friends I have, online or off.
