Am I in the wrong?

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.
