BABY MAMA DRAMA?

My boyfriend just moved into SC where I live. He has a apparent “baby mama” two states away who is apparently “9 weeks pregnant”. I believe she is lying to get him back. She says she’s pregnant with a girl, but at 8 weeks she can’t tell, right? Also, she has been drinking, the hospital gave her morphine. My boyfriend has another child who he can’t see, and so he’s pretended to still love her if she pregnant to see the “baby”because he doesn’t want this “baby” to turn out like his other son. He tells her whatever she wants to hear including “I love you” and “I want to be with you”. He tells me “I’m not a parent so I wouldn’t understand”. I’m also pregnant with his baby. She refuses to show any proof she’s pregnant.
