You may have started to change things but sometimes this will not be enough. Your partner may still be scared of you, or you may both feel that the relationship is over, or perhaps you need a break from each other so that you can think about what you both want. Or perhaps you feel that you can’t yet live safely with her and need to live apart for her safety.
A good dad wants his children to live without fear in their home so the best thing to do might be to leave for a while or for good, for everyone’s sake. It might not be forever and it doesn’t have to mean you don’t see the children. You may find that your relationship with your children improves if you and their mum aren’t living together.
If you’ve never used physical violence but have been abusing or controlling your partner in other ways, it still needs to stop and this may need to mean separation. She and your children deserve to live without this and the children will almost certainly have noticed that their mum isn’t happy.
Leaving safely helps your children to see you as a good dad and not a scary person or one who upsets their mum. It doesn’t matter if you think some of it is her fault or not, the children need to be able to feel safe and happy and they just want the fighting and arguing to stop.
You’ll want the children to enjoy being with you and this can happen when you are not frightening their mum and this can happen when you separate. In the long term, maybe you will change and maybe the relationship will be repaired. For now, you need to think about leaving safely.
