Pregnant Lesbian Figuring Out The Ground Rules For His Baby

I am a 32 year old pregnant lesbian. I fell into a trap, and either let him take my ass or he took my vagina. The morning after was when I had to face the possibility of getting pregnant, which is where I am. After a long, long discussion with my partner we've decided to accept the situation. Our financial reality will require his active support so we don't want to rock the boat.

He has agreed to financial support but with shared custody. He has a wife, so that really means his wife's custody, because I can't see him changing diapers. I asked him, what's the difference between two women, or three women, raising his child. But that's too much to ask a man.
