happy, please sit tight, my love. You have made an amazing, brave decision, it's so scary, I know, but you have done ABSOLUTELY the right thing.
If you go back, you are putting yourself - and your babies - in serious danger. This is a controlling, angry, abusive man, who has already broken your bones (and I bet that wasn't the first time something like that happened, was it?) If you go back, all you will do is give him a 'reason', so he will believe, to inflict even more damage on you. He won't be opening you with open arms, will he? He won't want to sit down and have a grown-up conversation about how you feel, will he? He will just teach you a bloody good lesson for stepping out of line, with his fists, won't he? You will be risking your life.
He does not own you. He has no right at all to tell you what to do, or how to behave, or what to wear. Real mean, good men, men who deserve your love, would never, ever do stuff like this. He is not normal.
Honestly, every one of us can well believe that you are terrified of what lies ahead. Everyone who has been in your situation has felt the same, I promise. You just have to keep putting one foot in front of the other. Please believe me when I say that your dcs will not thank you for going back to him. You say they'd be better off without you - I'm telling you categorically that they wouldn't. Don't do this to them.
