I never encourage divorce but it seems this is unsafe for you and the baby. I would think you both need time to get help for yourselves. 1 Corinthians 13 in the Bible is called the ‘love chapter’. It describes real love, not physical love, but love. It’s below.
"4 Love is patient, love is kind. It does not envy, it does not boast, it is not proud. 5 It is not rude, it is not self-seeking, it is not easily angered, it keeps no record of wrongs. 6 Love does not delight in evil but rejoices with the truth. 7 It always protects, always trusts, always hopes, always perseveres.
8 Love never fails. But where there are prophecies, they will cease; where there are tongues, they will be stilled; where there is knowledge, it will pass away. 9 For we know in part and we prophesy in part, 10 but when perfection comes, the imperfect disappears. 11 When I was a child, I talked like a child, I thought like a child, I reasoned like a child. When I became a man, I put childish ways behind me. 12 Now we see but a poor reflection as in a mirror; then we shall see face to face. Now I know in part; then I shall know fully, even as I am fully known.
13 And now these three remain: faith, hope and love. But the greatest of these is love."
I don’t see any of this is your relationship and it has to be there for it to work and have a decent respect for each other.
I think you should separate and get help soon before the baby has to deal with this terror too.
