Hi Garlic,
I've been lurking on this thread for a while.
I agree with PP that you are not to blame for this.
You accept that you can be head strong and determined and that this may have contributed towards his feelings of " being forced" into situations. You are willing to accept this and work on it though.
Having said that, he is an adult and should not have allowed himself to feel pushed into marriage or Ttc. He should have spoken to you sooner, especially given that you had noticed something was wrong.
I don't blame you for needing to get away that first night. You were in shock and not thinking clearly.
The way he has treated you since the split, not bothering to ask how you are, assuming you would just go away until he's decided what he wants etc is really cruel and you don't deserve it.
I won't offer any advice but I will say whether you reconcile or decide to split, you will be happy again.
