I agree with the first response. However, do not get caught up on "recovery time" two years or two months, it varies. I think you should be honest with person B. And I think you may want to try dating...trying out, causually meeting a couple people. I do not think that you are ready for a relationship. However, you can still keep your mind off of A and put yourself out there--you never know you may meet someone who fits better than A.
