What should I do?

My bf and I have been dating for a year now and first couple months he had to take breaks because he was trying to get over a girl and I let that be now it's a year later and the girl is back in his life and he told me he loves both of us equally and wants her to move in and have 2 women love him. Mind you I have 1 kid with him maybe 2 on the way. What do I do. Neither girl is into each other they are ex best friend and the other day the other girl tried taking her life bc I told her to never come back or around her bf again. He treated me like s*** for three days bc of this. Now he thinks everything is fine and won't have sex with me at all and he Evan waits for me to leave the room to release himself. Been this way since I found out I was pregnant.
