Seperated from my girls father three years ago. Very unhealthy relationship which got worse post separation. He was dealing with substance misuse/ mental health issues and I now realise there was DA. Initially there was some contact, however it was inconsistent, he wanted to let me know when he was available on a Monday for the week ahead which was a nightmare for trying to organise activities. He'd never let me know times of collection or drop off. He stated he didn't intend to have any contact 'while he sorted himself out'. Fast forward to now - no physical contact with all for 2.5 years, he's been advised that to proceed it needs to be a C100 but is yet to make an application. He will randomly text my DD once a year to ask how they are, that he misses them and he'll see them soon. I've never stopped phone contact. No acknowledgement on birthdays or Christmas. I want to do what is best for my children but contact is out of my hands now. I asked via third party for his consent to take the kids away abroad and he refused stating he would only sign if I let him see them. I'm so tired of it all. I don't understand why he isn't applying as he's been advised. I'm now in the process of seeing if I can apply for a SIO but feel sick with it all. Does anyone have any advice or been through similar?
