Why do you keep on saying 'what you lot don't understand is...' and 'what you lot continue to ignore is....' ?
We understand all of it and have not ignored any of it. Our opinions of your situation and the advice we have offered remain unchanged, in full consideration of the facts as you have presented them.
It seems you struggle with accepting that other people have a right to make decisions and hold opinions that you disagree with. Of course everyone struggles with that a bit initially, when they are dumped by someone they love it's a hammer blow to realise they don't feel the same way any longer.
There seems to be an awful lot of petulant foot stamping and dramatics from you and a belief that if you hound enough people then you (or them) can make him change his mind.
I appreciate that you say you've stopped now and will not be contacting any of them again, but if you've approached the end of your relationship in the same way that you've approached this thread then I can see why he won't sit down and have a civil discussion with you about his child just yet.
I know it all seems monumentally unfair, but maybe if you give him some space and calm the fuck down then that conversation will come later, so don't cut off your nose to spite your face on that score. Unless you genuinely believe he is abusive and not fit to be around your child in which case you should be relieved if he opts to stay away for good.
You have plenty of time to ruminate over all of that before the baby is born. There is no need to make snap decisions on anything right now. Allow yourself some time to recover from the trauma of the last couple of weeks, perhaps your CBT appointments will come through soon (especially if you tell your GP about the two harrassment claims against you, he might push for them a bit quicker) and perhaps you will get some help to see the wood for the trees a bit.
You said upthread that you went to his house to speak to him about your unborn child and he grabbed you and screamed in your face. What exactly happened during that encounter?
You say he's been abusive or violent four times in eight months but you don't mention specifics apart from to say he 'grabbed' you on that occasion.
That was obviously a very emotionally charged situation and one where you were subsequently accused of harassment, so I can imagine that as the police haven't rushed to charge him he has presented a very plausible 'other side' to the story. Were there witnesses?
I know it's all still very fresh and raw for you but you are in danger of getting yourself into some serious trouble if you are not careful. You've started something now by involving the police out of what, to be frank, sounds like it was motivated by pure spite. The police will already have information on you from the last time you were investigated for harassment so even if you were 'proved innocent' then, a second harassment accusation so soon after and with a totally different 'victim' will not bode well for you at all, so be very careful how you choose to approach this.
