He is in a terrible state because he is not in control of you anymore.
Don't kid yourself that this is remorse. Seriously. YOUR feelings mean NOTHING. He wants to come home cos he is worried about how it looks and what it means about him. NOT that he assaulted you. YOU mean NOTHING. Your DD means nothing. Trust me.
The panic I saw on my Ex's face the day I took him to the airport was terrifying, I went into shock. he knew he'd lost me and he unravelled before my eyes.
Your H kicked you (that was my Ex's prime choice of assault) to kick someone shows a level of disgust and resentment that is off the charts. seriously.
You are wobbling, told you that you would. Your reasons are your reasons, mine are mine. The suffering I had to deal with was immense, some here know what I went through. Ex was rarely violent, but psychologically cruel and my day to day was mostly a torturous existence.
So your's kept you in a golden cage, to the outside world all is wonderful, but when the excuse came, a few drinks, and he let himself free. He repeatedly called you a Cunt, kicked you and smashed a valuable item of yours, one that could be used by you to summon for help. IN. FRONT. OF. YOUR. DAUGHTER.
Mine never called me a Cunt, nor attacked me in front of a child old enough to understand; he kicked when our DS was out of sight. Except once he threw something at me, DS was in the next room, heard the crash only, but that alone gave my 5yo nightmares for weeks.
Your's attacked you so badly the police took him away. If he does this now, what about the next time? You know there will be a 6th time, if you let him back.
What about when your DD grows up and challenges him? He WILL hit her.
yes things may be a little tight for a while, but he will pay maintenance for her, and you will put your life back together, you will grow, you will see how much time you lost. You will cry, you will feel stupid, but you will see that none of this was your choice for him to treat you like this.
Please get the Lundy Book? please download it if you can? it really will answer all your questions, it'll help you see how futile it is to try to give them the benefit of the doubt. Once you see that, everything gets so much easier, so much clearer.
