I am fairly new to SE, so I came here to ask for advice from more experienced users.
Sometimes the author of a question comments my answer to ask for clarification or because they don't agree on some point I made. I usually edit the answer in order to address their query. In one occasion though, the discussion with the asker went on in the comments and eventually I migrated it to the chat and has been going on for some days.
At this point I have the feeling that the problem will never be resolved in this manner, I feel we don't have many points of contact, probably due to a very different background, but we seem to hardly agree on anything.
The discussion is stalled and I have the temptation to just disengage, but I feel bad for not being able to help the asker.
Have you ever been in a similar situation? What behavior do you suggest?
As a side note, this situation happened in physics.SE, but I am asking here because I feel that this community is more welcoming than physics and I am having a good time here, you are great people. The question is relevant here too, because the same situation might happen here in the future.
