unfaithful

During the trial, Holly has been portrayed by him to be a nasty, unfaithful girlfriend who had multiple boyfriends, this could not be further from the truth.

Stewart said the act was “neither naughty nor unfaithful.”

Ms Trussler said during the trial MacPhail had attempted to portray her "caring, kind daughter" as a "nasty, unfaithful girlfriend" but that "could not be further from the truth".

“This is something that happens to a lot of women who get blamed when they have the courage to leave an unhealthy relationship and are labeled as being unfaithful,” she said.
