Boyfriend of 3 years acting crazy since I got pregnant

I’ve been with my boyfriend (33) for three years. To be honest, he has always been "bad" in terms of his behavior—he’s been physically and mentally abusive in the past. But since I found out I’m pregnant, something has shifted and it’s the most hurtful it’s ever been.

I’m trying to get a straight answer from him about what he wants or what we should do, but he won't give me one. He just talks in circles or sends nonsense. I feel completely alone and I can’t think straight.

Here is exactly how our last conversation went:

Me: I really need to talk to you about this.

Him: Bosnians. J jdjjejxjdyjcjfhc. Xbhshurt. She. Manchus.

Me: Omg please, it’s not a joke. Just tell me what you want!

Him: Fuck my face. Just stop right now. Please. If you want take the pill. We need to talk more.

Me: We need to talk more about what? Please tell me what you want.

Him: We are dumb.

Me: Why? What do you want?????

Him: Fucking A woman. Stop asking you don’t listen! But we gunna hate each other either way after all this shit so.

Me: Say it!!! Just say it, please. You’re so hurtful. I’m not being mean. I just want you to tell me. I will listen. Please just tell.

He is being so dismissive and aggressive. He blames me for "not listening" even though he isn't saying anything clear. He is working out of town but I live with him and almost think I need to pack my stuff and go before he gets back.

Has anyone else dealt with a partner who uses this kind of "word salad" or gibberish to avoid a serious conversation? I’m scared and I don’t know how to handle this on my own.
