Help!

Is it bad to be so stressed and cry every night while pregnant? Can anything happen to the baby? I'm being emotionally and mentally abused by the father of my unborn. I feel lost and alone. And it just seems to be getting worse. He starts arguments and apparently it's my doing. I'm the one to blame. And then after blaming me he says I'm not blaming you. But yet calls me and emotional manipulative bitch. I'm quiet, I let things build up and I break down when I can't take it no more.
