Married At First Sight's Zoe Hendrix has claimed that Alex Garner "walked away" from their relationship after three years together.
The couple, who were one of the reality TV show's few success stories, announced their surprise split in April.
Hendrix and Garner share one-year-old daughter Harper and had previously announced plans to tie the knot legally.
Responding to fans who had asked her why she had left Garner, Hendrix wrote on Instagram that she had never thought she would be a single parent.
