What is going on? advice from everyone please?

I just moved in with my boyfriend and we got into a pretty bad argument and he over did it, he became very mean and aggressive then kicked me out. By the end of the day he was crying and asked me to come back home and was sorry and really loved me and knew we could get past this. I also found out I am pregnant and told him I did not feel ready to have a child. He said abortion was not an option and if I didn’t want the kid he would raise it on his own. Few days later we got into an argument again and he got very mad at me and said he was done and he did not want me to move back in. He said I was toxic and kept playing with his emotions and only stressing him out. He told me he was going to go out and hook up with other girls etc. I was hurt and mad so I sent him a picture of me with my ex. Since then he has been acting like he does not want to be with me anymore and said he does not care if I get an abortion and he is not worried about me anymore. I am very sad and I have expressed to him how much I miss him and still love him and how I don’t understand how he can switch up so quick. He said I did this and I made my bed and I need to lay on it. Why is he being like this?
