So sorry you are going through all this Middie, especially right now.

While I do defer to the professionals when they advise to give him a little time (if only due to them being actual professionals), I still maintain it is absolutely incredulous and entirely unacceptable that he would knock you down in an attempt to get his phone back, regardless of the pregnancy. The fact you are pregnant and that still happened only amplifies how astoundingly...I dare say cruel...the act was.

To me, I would think if he didn't have anything to hide, he wouldn't have made such a drastic attempt to keep you away from the phone. To physically knock you down, especially while expecting, signals to me a huge red flag.
I hope he will come around...he does you and your child a massive injustice by not being there for you. While I hope and pray you two are able to reconcile, if things don't work out that way, you owe it to yourself and to your child to get whatever support from him that you can. It is, after all, his child as well...he owes you at the very least that much.
You are in my thoughts and prayers as you go through this. Please keep us posted, and congratulations on the baby girl.
Hugs,
Harley
