Home and Away - Leah Patterson-Baker will be left devastated after calling off her engagement to Zac MacGuire.

To add to the already-palpable tension, Charlotte and Hunter are going to extreme efforts to ensure that they get Zac all to themselves, leaving Leah to feel increasingly isolated.

However, the situation will reach breaking point when an upset Leah (Ada Nicodemou) witnesses a happy moment between Zac, Charlotte and Hunter on the pier.

Unable to cope with the situation any longer, Leah later tells Zac back at home that as he is unable to choose between her and his son, she is making the decision for him.

Leah then takes off her engagement ring and walks out, but is it really the end of the road for the pair?
