I cannot stress enough that ‘you and him’ are not the problem. HE is the problem.
many of us have been in toxic relationships where we end of winding each other up. I have. The thing is, that in basically safe adults - that incompatibility doesn’t go beyond arguments + breaking up. It certainly wouldn’t involve the police.
in order for someone to be remanded in custody. They have to be considered to be a serious threat. This person is NOT SAFE. This is NOT YOUR FAULT.
sometimes we get conditioned to think big drama + fighting is because there is so much big feeling / love. It isn’t. Real love holds the safety of you and your family as sacrosanct. It isn’t scary.
Your two year old daughter will be much better served by a safe happy mum than anything else. Do your therapy, work the freedom program, build yourself up, create a beautiful life.
IF her father shows remorse, does his own therapy, works an anger management program + chooses to try build a relationship with her then he can do that on the other side. And you can discuss with social services + your therapist whether that feels safe.
