I’m in love with my best friend please help?

Eli Kingston Asked: I’m in love with my best friend please help?

My best friend is a girl, we have been best friends for ages, we have dated once even and we lasted as well, then after we broke up it only took us about a week or two to be back to normal and best friends again, we even both saw other people, neither of us were jealous of these other people back then either. After we broke up if we were both single we would have sex every now and then, nothing more though. But now she is pregnant with what may be my baby (she was in a bad relationship and she ended up cheating on him with me) and so there is a 50% chance the baby is mine. But that is not my concern, because regardless of whether the child is mine or not i will help raise her anyway because shes my best friend. The real problem for me is that i have fallen back in love with her and she is in a relationship with another guy who isnt one of the possible fathers of her child. He drives me insane when he calls the baby "his" and she just lets him anyway. She said she always has had feelings for me too but that she doesnt know what to do because she still likes her relationship she is in. And I have to see them together all the time because shes my best friend and he has been taking her away from me and i never see her much, and i can hardly ever see her alone. And he lies and tells everyone that he is the bio father. I dont know what to do its left me in one of those emotional breakdowns where i dont even know what emotion i am feeling. What i need to know i guess is; how do i win her back without pressuring her? and how do i get rid of this other guy and the **** he babbles on?she is 6 months pregnant please help me, i need to get rid of him before the baby comes, i dont want him stealing away the joy of parenting and all that from me, it should be my joy, any opinion is welcome negative or positive
