I think it's really concerning that you're more worried about the impact it could have on his career if you said the wrong thing than the impact the violence he has already shown will have on your child (although for some reason you seem to be deep in denial that it even was violence).
You know this is all very, very wrong or you wouldn't be worried about saying the wrong thing to the counsellor. However you also say that you'd like him to punch you to make it easier to leave - but leaving isn't ever likely to feel 'easy', people stay in violent relationships all the time for that very reason and the chances are you'll find a way to minimise and excuse the next time he is violent, just like you have the last one. I walked into the door, he didn't mean to do it so hard, he didn't break anything it's just bruised, I shouldn't have said what I said. That's what happens.
But you deserve better and your child deserves better, he or she is learning what relationships look like, how men treat women and how men and women behave. They are growing up in constant tension, with a mother who is always on edge and father who is a nasty, violent bully, that is what they are learning from you - and you need to do whatever it takes to leave so they don't grow up in fear.
Tell your counsellor the truth and tell her that you need help to leave but you are terrified - or phone womens aid and talk to them. If you can't do it for yourself because he has taken away all your self worth and self esteem then do it for your child.
You're desperate for someone who is abusive to love you - you cannot make. force, cajole, encourage or persuade someone to love you, they either feel it or they don't. You are absolutely fighting a losing battle there and yo will always lose. I'd suggest though that it isn't love you feel at all, it's emotional dependence - a healthy loving relationship isn't one sided, or violent, or degrading or emotionally abusive or gas lighting or any of a long list of things that this is. Where did you learn that this is what love is and that you are desperate for it?
