I once has a girl follow up 2 weeks later asking why we didn’t go on a date? I told her that was the first question she asked me and I felt she wasn’t into the conversation.
I do wonder sometimes what they're thinking. Like, do they think the conversation is going well when I have to keep resuscitating it?
I'm told people have "different communication styles", which is fine, but "not asking questions and giving really short answers" doesn't seem like an effective style here. Like, if someone's chatting you up at the bar and you're not interested, then giving short answers can make a kind of sense. But in a dating app where you both showed interest? If you're no longer interested just unmatch.
What is the discomfort? Are you afraid something will happen?
You should probably talk to a professional about this. I am not a professional, alas.
