Your boyfriend cheated on you while you were pregnant with his child what do you do?

If you are completely sure he cheated and he admitted it, i would leave him and tell him he can visit the baby when it is born as long as he doesn't bring the cheatee (the person he cheated with) and he can visit the baby whenever he wants for a reasonable time AT a reasonable time. If your not sure, confront him about it and if he admits cheating then i would give him one last chance because he showed his loyalty to you by telling the truth, but make it very clear it's his last chance and if he cheats again then he can be out of the baby's life . if he says no he didn't i would just believe him because if he truly loves you then he wouldn't lie.
