So i opened a case with the child maintenance service because my daughters dad is always been abusive and controlling, it seems to be a pattern of behaviour with him. His messages are very much domestic abuse and controlling which I have noted to the police and csa and stopped contact however he has managed to bypass this and tried to follow me on Instagram to try and get a reaction off me so I ignored it. Then I noticed he was writing enjoy and have fun and other sarcastic comments on the bank reference. Hr has been abusive from the start regarding child maintenance but he has never had anything to do with my daughter (3) and has never offered any kind of contribution so as a single parent I had no choice to claim financially. This helps with nursery costs, clothing etc. child maintenance have stated they won’t do anything but it seems he is using any form of contact to continue the abuse and get me to shut down the case. I hate the man so much and sometimes I’m glad he has nothing to do with my daughter because I really don’t want this abusive behaviour around her or him treating her like this.
