He is either married or lives with the woman or at least involved . From the way it looks he is cheating on her with you.

Of course when the little one goes there the woman is there as they are a couple. There is really nothing you can do about that but most certainly you can stop sleeping with him. If you believe it's bad for your child to go to their home you can petition courts to make visitations supervised or what not but most likely judge would deny it. If your baby is treated well in dads home there is nothing you can do.

Saying all that I would be upset if my daughter called other women "mom" I am her only mother. But that's why you don't mess with low class men like this one. Stop sleeping with him. What if you get pregnant again???
