Hello Lizzie
im so sorry to read your heartache, especially with a beautiful little girl who loves her daddy. This must be so difficult for you. You also should be so proud of yourself having the courage to walk away and get help for yourself, which in turn has helped him along the way.
no wonder your suffering with anxiety, have you been to the doctor for help or a therapist to talk too as you have been through a traumatic experience. You sound like a strong woman dig deep to find her again and remember your not at fault, you are amazing. You need to put yourself first so you can look after your little girl.
I do hope that rehab is working for him and he realises what he put you both through.
Are you in touch with his family to find out how he is doing.
remeber you and your little girl comes first, look after yourself, stay strong and true to yourself
thinking of you
