In my personal experience, every bishop has a different approach. But each has the spirit of discernment to understand your situation and what the Lord wants for you. If he said he didn’t need details and that the Lord is happy with your repentance and to move forward strengthening your relationship with God, then that’s all that matters. No need to dredge up past wrongdoing with every bishop in the future.

The one other thing I would add is that if you are planning on marrying your boyfriend, to trust him enough with that as well. For good or I’ll it will show him what kind of person you want to be in the relationship going forward and what kind of a person he is depending on the reaction.

I would also add, that you need to forgive yourself for any justification of sin. We can often times be our own worst critic and hinder ourselves from growth by not moving past our own follies.

I think Jesus said to the woman who washed his feet with her tears to go her way and sin no more. He didn’t say to go her way and make sure to discuss it with all future leaders. When your sins are washed away, it is as if they never happened.
