I understand the thinking here but...
If in your head it was "too dangerous" to turn around, why do you think your brain decided it was safer to continue?
How deep is this cave and what gas were you breathing?
We were on air, #1 and I on backmount, #2 sidemount.
Average depth of that cave is around 18-20m.
My thinking must have been along the lines of “hey, there are my buddies over there with redundant gas supply and experience in that cave, I see them so I will do a blind jump against the rules to get to them as I just realized I effed up and am on the wrong line” versus “ I just realized I am on the wrong line, first time in this cave and might not have been paying attention to my navigation up until this point so although I know I can turn around and get back to exit I am not so sure if I didn’t miss any navigational points; plus I am not happy with being solo in the new cave just with my twinset.”
In a more familiar cave when I couldn’t get past restriction which they both navigated through ahead of me, I backed off the cloud of silt, deployed my marked arrow on the line to point to my exit and was ready to deploy my back up light, attaching it to the line to shine on my arrow towards exit direction to let them know I turned around to exit. Before I finished #2 came back to check why am I not coming through.
The above makes me think that unfamiliarity with a new cave made me choose what I did.
