my ex hates me and I can't change that

Q: My son's dad simply ignores my questions when he doesn't feel like answering. I am trying so hard to be flexible, co-operative, kind, helpful, and even forgiving in the face of his hurtful, mean-spirited manner and downright rude behavior. I feel so angry I get to tears. I can't yell, scream, or curse, so I end up crying. I feel so hurt that this man I made a child with could treat me so terribly. I don't know how to deal with it. I can't do this alone. He hates me and I can't change it. No matter how nice I am or the nice things I do, they are disregarded in an instant if he is angry. He's almost got me believing he's right. We can't co-parent. It might be impossible.
