Jennifer Butler, 29, will travel to Texas to marry 23-year-old Christopher Mosier who is in prison for drug offences.
She will leave behind her three children, all under 10, when she leaves for the States, but Butler remains unrepentant about her decision.

'Some people might think I'm bonkers for falling in love with a prisoner. And not everyone will agree with our relationship' Butler told The Sun. 'But Chris is a wonderful man. Sure, he made a few mistakes in the past, but everybody deserves a second chance.'
Single mother Jennifer began writing to Mosier in July 2013, after finding him on a website called writeaprisoner.com.
Butler said she felt an instant connection with Christopher, who was sentenced to 15 years in 2009 for burglary with deadly conduct, and wanted to be a friend to him.
Love blossomed over the months they spent writing to each other, with Butler eventually flying out in October to meet him.

'We had a glass window between us and had to talk through a phone. When I saw him walking down the corridor knew he was the man for me. We talked for four hours and it felt like I'd known him all my life.'
Mosier proposed in April with a piece of grey string for a ring, and Butler now plans to move to America to be with him when he is released in September.
