If you were d by your exhusband while unconscience, and dont remember until 3 years...?

Perhaps you were d and perhaps you weren't. You have a terrible memory, and whatever flashbacks are, they are not very reliable. If you were d, you should be very upset. If you were, or suspect that you were d, I am not sure that you could "just forget about it". NOr do I think that there is much recourse.
