how is curley's wife's loneliness shown during critical incidents

Whenever Curley's wife shows up we see her loneliness. It pours out of her in resentment and disillusion.

"I never get to talk to nobody. I get awful lonely."

"What's the matter with me? Ain't I got a right to talk to nobody?"

"Seems like they ain't none of them cares how I gotta live".

Try to read what she is saying here. She blames others (rightly so) but feels so disenfranchised that she does not know who she is anymore.

Page 87, just prior to her death; "I get lonely," she said, You can talk to people, but I can't talk to nobody but Curly. Else he gets mad. How'd you like not to talk to anybody?"
