‘We never left your side, your dad and I. You’re so big now and strong. I’m so blessed to have you.’

‘He was always very supportive and I had terrible post-natal depression which is my motivation behind my charity. 

‘He took the kids when I was in no state to have them. I had to fix myself and I was alone. He was great to me. 

‘He still emotionally supports me and my decisions, helps me with relationship advice and also looks out for me and my children’s happiness.

‘We still share kids birthdays together and do lunches. We just can’t be together because we argue and we both have a lot of damage from our past which clashes.’
