8 months pregnant and my boyfriend of 3 years just walked out on me....

I came home from work exhausted and I guess I started to “bitch” because he’s home all day and didn’t help me clean. Who wants to come home from work and clean a mess? So he got upset and showered and packed all his clothes and everything and left me. He said he’s moving to his friends house. But I don’t know why all of a sudden he wanted to leave out of all days. He didn’t want to talk or give me a good reason to anything. He said he couldn’t deal with me anymore? All I do is go to work and come home and clean and do everything he asks of me.. it hurts so much that he walked out on me and I’m pregnant carrying his baby... idk what to do. I know I have to be strong for my daughter but it hurts so bad 😭

Update question: should I even call him or notify him when it’s time to give birth to our daughter?.... I’m so conflicted..
