Pam I did something similar, long story short we are very happy today. It has been 4 years and I had BP for 7 of them. But you need to have a heart to heart with hubby. BP or not, things do happen and people do make mistakes sometimes. You have to first be sorry that you did this and tell him and then ask him what you can do to gain his trust, assuming you still love him, that is why you posted this, then maybe see a counselor or get a marriage help book?
I dont know the right answer for YOU but you definately need to talk about this esp since the call was your dad.
Maybe you can agree to a compromise. I know it seems so hard right now, me and my hubby went through this and it took a year to get it all set.
Now sometimes I even think about the past and regret and hate myself. The thing is that he really did forgive me and that is why.
Question is, does your husband really forgive you? That is up to him and even if you ask you cant make him.
But if he can forgive you, it also may take time, so you two need to be talking about everything and keep it all open communication, If you dont the marriage will fall apart.
He may want you to do certain things to prove you wont do this again, maybe you can let him answer the phone, if you have nothing to hide? I dont know, that is up to you, but keep the communication that is the only way it can work. There is a lot to do, I know but you will get there if you show him you are willing. Episodes or not, that is beside the point. Make sure he knows about BP and how it affects you.

Well I wish you the best of luck!
