Please give me advice asap?

me and my boyfriend planned to have a baby we was so happy now that im pregnant and we have been having problems he is not the same . he n0t the person i once fell in love with now he thinks i never cared about him and he is done with me and dont love me and dont want t0 be with me any more but if i did something wrong i would fight for love but instead he talk to me about how many females like him and how fine and sexy they are so i see there is no need for me to try anymore and he tell me if i dont come when he say come he is going to call another female so every since then i pay him no mind and he t0ld me not to talk to him . Ok. Now that he was out late he text me saying why i didnt check on him and he really hates me and that he cant wait till i have the babe so that he can get coustdy because he hate me aha thats not something you get coustdy for lol. But if he wants me to care and want us back why not tell me instead of say all these hate ful things i dont get him and he said he want us not together ok then why is he mad at me? What should i do im pregnant and already have a job in school and takeing care my son on my own and trying to better my life for my next baby because my kids are my first priority and they matter more then anything but what do i do about him ?
