who is your baby father

I had the baby still don't know who the father is, but taking it one day at a time. My husband doesn'tknow, it's a possibility it's not his and I haven't, told the married man she's born, even though he knows I was pregnant, I'm just thinking about leaving it as though my husband is the father!!!
Update: I'm going to tell the married man that the baby is here so her can the test, that way if it's my husband I never have to tell him, but if it's the married man than I'll tell him the truth,
