You are a strong woman. You deserve love and peace and happiness, and so does your daughter. He may regret his actions, but he may never, and that is the downfall to every situation.
If he never comes back, know you are strong enough to build a life with your daughter, in your family home. I believe in you. You can come back from this and one day you will say to yourself, 'Oh, God, how did you ever help me through this'.
