The pair are going through a tough time in their relationship, and it is said that Warne's failure to commit to tying the knot is the reason behind their split, reported Contactmusic.
"She kept pushing for a date but he was happy as things stood. She ended it furiously. She started to question whether Shane had any intention of marrying her. She feels let down.
They had big, big plans. She really thought she had found 'the one' in Shane. He could have easily saved the relationship by agreeing to a definite date," a source said.
Hurley is said to be devastated by the way their relationship has headed because marriage certainly seemed to be in their future.
"She is devastated about the way things stand as she feels she has invested a lot in their relationship which was, until recently, heading towards the ultimate goal of marriage," the source added.
